Slight preference for removing this comment. I think it's pretty clear what the function does from the body, and it's pretty likely it will grow out of date if the logic is ever updated.

Makes sense, removed

You might consider asserting on the can AST (you could print it back using
) or adding tests in test_mono to assert the code generation is as expectedThere was a problem hiding this comment.
I moved the tests to test_mono because that seemed simpler.
Traverse pattern ASTs and desugar two cases - Desugar optional record field default value expr. This expr might contain nodes that need to be desugared, such as binary operations. Failing to desugar this expr can cause an internal panic later in canonicalization. - Discard SpaceBefore and SpaceAfter nodes so that patterns can be destructured over multiple lines. Keeping these nodes can cause an internal panic later in canonicalization. Fixes [1]. [1]: roc-lang#5653.
