| # Test that lowering doesn't accidentally put a `Module` in the Method name slot | ||
| let src = @Meta.lower let capture=1 | ||
| global foo_lower_block |
There was a problem hiding this comment.
IIUC, the reason this must be in lowering (and wrong to inspect the signature unless lowering instructs that it must) is that this line could be:
Suggested change
| global foo_lower_block | |
| global const foo_lower_block = Base.redirect_stdin |
And looking at the signature would wrongly name this Method as Base.RedirectStdStream(0), when syntactically it has the different intended name foo_lower_block

The `:outerref` removal (#54772) ended up accidentally putting a `Module` argument into 3-argument `:method` due to a bad refactor. We didn't catch this in the tests, because the name slot of 3-argument `:method` is unused (except for external method tables), but ordinarily contains the same data as 1-argument `:method`. That said, some packages in the Revise universe look at this (arguably incorrectly, since they should be looking at the signature instead), so it should be correct until we fix Revise, at which point we may just want to always pass `false` here.
