Parser fails on inlining nested blocks

[smarr]

In SOMns, the following code is problematic:

  false whileFalse: [
    | resrv |
    critical: [ resrv ] ] ].

The inlining of whileFalse: did not properly initialize the inliner with the local variables of the inlined block. This was covered up by on-demand adding the local information for writes.

A solution and tests are here: smarr/SOMns#72
