There was a problem hiding this comment.
Thanks!
Perhaps it might be even better to name the specific Rust version where drop flags were moved out of Drop types and onto the stack. I believe that's tied to MIR, but I haven't managed to confirm about a specific Rust version in regards to the drop flags.
I think it's not a big deal as it should be quite old. I'm going to merge as-is.

This sentence originally confused me and it took me a while to realize that it was referring to an older Rust version rather than some edge case of drop flags in the current Rust version.
Perhaps it might be even better to name the specific Rust version where drop flags were moved out of Drop types and onto the stack. I believe that's tied to MIR, but I haven't managed to confirm about a specific Rust version in regards to the drop flags.
