Description
When looking at this source file in the rayon project, expanding the multizip_impls! macro call does not fully expand, with some nest! macros remaining unexpanded. I've tried an older version where instead the expansion was complete, so this is a regression. The older version I tried was 0.3.2370-standalone, but I didn't look for the last version where that was working.
I was actually made aware of this problem by using rust-analyzer as an analysis library. As far as I know, this was last seen working at version 0.0.274 of the rust-analyzer crates, like other issues that were fixed in the meantime (#19873 and #19931, which may be related). I also have a case that seems similar to this on a private repository, but I think that if the rayon case gets fixed, it should also happen to the other case.
rust-analyzer version: 0.3.2500-standalone
rustc version: 1.87.0
editor or extension: VSCode version 0.3.2500
