  = help: if you intended `T` to be a const parameter, use `const T: /* Type */` instead

error: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.78.0-dev running on x86_64-unknown-linux-gnu

[compiler-errors]

This is precisely the bug that I pointed out in #117246 (comment)

The correct fix here would be to re-land #111020 with a proper lint -> warning period -> hard error transition.
