But in fact, since the expression @racket[(get-f 1)] happens to be fully qualified with all the arguments it needs, the currying employed under the hood to implement partial application in this case @seclink["Using_Racket_to_Define_Flows"]{evaluates to a function result right away}. This then receives the value @racket[3], and consequently, this expression produces the correct result. So in sum, it's perhaps best to rely on @racket[esc] in such cases to be as explicit as possible about what you mean, rather than rely on quirks of the implementation that are revealed at this boundary between two languages.

This is a conservative starting point and won't always find the most optimal solutions, but is a worthy place to start and will give us clues over time on how to handle cases that elude this paradigm. --- qi-lib/flow/core/compiler.rkt | 46 ++++++++++++++++++++++------- qi-lib/info.rkt | 1 + qi-sdk/profile/nonlocal/qi/main.rkt | 22 ++++++++++++-- qi-test/tests/flow.rkt | 9 +++++- 4 files changed, 65 insertions(+), 13 deletions(-) diff --git a/qi-lib/flow/core/compiler.rkt b/qi-lib/flow/core/compiler.rkt index e7298ea0..1c438968 100644 --- a/qi-lib/flow/core/compiler.rkt +++ b/qi-lib/flow/core/compiler.rkt @@ -42,6 +42,9 @@ (#%host-expression f))) #:attr next #'filter-cstream-next)) + (define-syntax-class non-fusable + (pattern (~not _:fusable-list-operation))) + (define (generate-fused-operation ops) (syntax-parse (reverse ops) [(op:fusable-list-operation ...) @@ -51,14 +54,11 @@ list->cstream-next)) lst)))])) - (define (optimization-pass stx) + (define (normalize-rewrites stx) ;; TODO: the "active" components of the expansions should be ;; optimized, i.e. they should be wrapped with a recursive ;; call to the optimizer (syntax-parse stx - ;; stream fusion for list operations - [((~datum thread) f:fusable-list-operation ...+) - (generate-fused-operation (attribute f))] ;; restorative optimization for "all" [((~datum thread) ((~datum amp) onex) (~datum AND)) #`(esc (give (curry andmap #,(compile-flow #'onex))))] @@ -68,7 +68,7 @@ #'(thread _0 ...

It also allows us to deal with the concept of chirality only in the expander and largely deal only in terms of explicit templates in the compiler. The only place where we still need chirality in the compiler is in `clos`, which is a way to pre-supply arguments at runtime rather than at compile time. There's no obvious syntactic way to designate which side the pre-supplied arguments should be placed on here. We could introduce `clos` and `closr` core forms to differentiate these cases but that doesn't really simplify it (although it would be another step in the direction of making our core language explicit and not reliant on syntax properties). --- qi-lib/flow/core/compiler.rkt | 23 ++++----------------- qi-lib/flow/extended/expander.rkt | 34 ++++++++++++++++++++++--------- qi-lib/flow/extended/syntax.rkt | 8 +++++++- 3 files changed, 35 insertions(+), 30 deletions(-) diff --git a/qi-lib/flow/core/compiler.rkt b/qi-lib/flow/core/compiler.rkt index ea6c6f54..9289a890 100644 --- a/qi-lib/flow/core/compiler.rkt +++ b/qi-lib/flow/core/compiler.rkt @@ -255,23 +255,6 @@ [((~datum #%fine-template) (prarg-pre ...

In the most common cases there will be no difference to the result, but if the flow is invoked multiple times (for instance, if it were first defined as @racket[(define-flow my-flow (☯ ((get-f 1) _)))]), then the expression too would be evaluated multiple times, producing different functions each time. This may be computationally more expensive than using @racket[esc], and also, if either @racket[get-f] or the function it produces is stateful in any way (for instance, if it is a @hyperlink["https://www.gnu.org/software/guile/manual/html_node/Closure.html"]{closure} or if there is any randomness involved), then this version would also produce different results than the @racket[esc] version. -Another way to do it is to simply promote the expression out of the nest: - -@racketblock[ - (~> (3) (get-f 1)) - ] - -@;{TODO: Update this to reflect new partial application behavior} -Now, you might, once again, expect this to be treated as a partial application template, so that this would be equivalent to @racket[(get-f 3 1)] and would raise an error.

To understand it holistically would require a history lesson to put the sunyata development in context, and that would be quite a digression. But in essence, sunyata is about transcension of context or viewpoint. A viewpoint is identifiable with a logical span of possibilities (@emph{catuṣkoṭi}) in terms of which assertions may be made. Sunyata is the rejection of @emph{all} of the available logical possibilities, thus transcending the very framing of the problem (this is signified by the word @emph{mu} in Zen). This kind of transcension could suggest alternative points of view, but more precisely, does not indicate a point of view (which isn't the same as being ambivalent or even agnostic). This idea has implications not just for formal logical systems but also for everyday experience and profound metaphysical questions alike.

Note however that if the functions used in @racket[filter] and @racket[map] are not @emph{pure}, that is, if they perform side effects like printing to the screen or writing to a file, then the Qi flow would exhibit a different @seclink["Order_of_Effects"]{order of effects} than the Racket version. + @section{Curbing Curries and Losing Lambdas} Since flows are just functions, you can use them anywhere that you would normally use a function. In particular, they are often a clearer alternative to using @hyperlink["https://en.wikipedia.org/wiki/Currying"]{currying} or @seclink["lambda" #:doc '(lib "scribblings/guide/guide.scrbl")]{lambdas}.

Such values can be useful as side effects, for instance to capture some idea of statefulness, perhaps keeping track of the number of times a @tech{flow} was invoked. But they should generally not be used as inputs to a flow, especially if they are to be mutated. -@subsection{Order of Effects} +@subsubsection{Order of Effects} Qi flows may exhibit a different order of effects (in the functional programming sense) than equivalent Racket functions.
