FWIW, my dmd bug fix PR is getting languish-y. https://github.com/dlang/dmd/pull/8051
Ideally a good bug fix shouldn't sit around for a week. Why I'd call this one good:
* in addition to reported bug (struct initializer incorrectly parsed as function literal), a read of the code uncovered converse as well (function literal incorrectly parsed as struct literal). PR fixes both and adds test cases.
* documents additional ambiguous parser cases, and why we resolve the ambiguous cases as we do, and how to work around it. Added unit tests to confirm handling of ambiguous cases.
What went well: appveyor flagged a regression which sent me back to the drawing board, resulting in a much better fix
