/**
* @typedef {(template: TemplateStringsArray | string[], ...args: any) => DetailsToken} DetailsTag
*
* Use the `details` function as a template literal tag to create
* informative error messages. The assertion functions take such messages
* as optional arguments:
* ```js
* assert(sky.isBlue(), details`${sky.color} should be "blue"`);
* ```
* // TODO Update SES-shim to new convention, where `details` is
* // renamed to `X` rather than `d`.
* or following the normal convention to locally rename `details` to `d`
* and `quote` to `q` like `const { details: d, quote: q } = assert;`:
* ```js
* assert(sky.isBlue(), d`${sky.color} should be "blue"`);
* ```
* However, note that in most cases it is preferable to instead use the `Fail`
* template literal tag (which has the same input signature as `details`
* but automatically creates and throws an error):
* ```js
* sky.isBlue() || Fail`${sky.color} should be "blue"`;
* ```
*
* The details template tag returns a `DetailsToken` object that can print
* itself with the formatted message in two ways.
* It will report full details to the console, but
* mask embedded substitution values with their typeof information in the thrown error
* to prevent revealing secrets up the exceptional path. In the example
* above, the thrown error may reveal only that `sky.color` is a string,
* whereas the same diagnostic printed to the console reveals that the
* sky was green. This masking can be disabled for an individual substitution value
* using `quote`.
*
* The `raw` property of an input template array is ignored, so a simple
* array of strings may be provided directly.

/**
* @typedef {(template: TemplateStringsArray | string[], ...args: any) => never} FailTag
*
* Use the `Fail` function as a template literal tag to efficiently
* create and throw a `details`-style error only when a condition is not satisfied.
* ```js
* condition || Fail`...complaint...`;
* ```
* This avoids the overhead of creating usually-unnecessary errors like
* ```js
* assert(condition, details`...complaint...`);
* ```
* while improving readability over alternatives like
* ```js
* condition || assert.fail(details`...complaint...`);
* ```
*
* However, due to current weakness in TypeScript, static reasoning
* is less powerful with the `||` patterns than with an `assert` call.
* Until/unless https://github.com/microsoft/TypeScript/issues/51426 is fixed,
* for `||`-style assertions where this loss of static reasoning is a problem,
* instead express the assertion as
* ```js
* if (!condition) {
* Fail`...complaint...`;
* }
* ```
* or, if needed,
* ```js
* if (!condition) {
* // `throw` is noop since `Fail` throws, but it improves static analysis
* throw Fail`...complaint...`;
* }
* ```

/**
* assert that expr is truthy, with an optional details to describe
* the assertion. It is a tagged template literal like
* ```js
* assert(expr, details`....`);`
* ```
*
* The literal portions of the template are assumed non-sensitive, as
* are the `typeof` types of the substitution values. These are
* assembled into the thrown error message. The actual contents of the
* substitution values are assumed sensitive, to be revealed to
* the console only. We assume only the virtual platform's owner can read
* what is written to the console, where the owner is in a privileged
* position over computation running on that platform.
*
* The optional `optDetails` can be a string for backwards compatibility
* with the nodejs assertion library.
