Regression of the typenum crate on nightly #32637
Description
The typenum crate (as of paholg/typenum@10c15e3 at least) successfully compiles on stable/beta but fails to compile no nightly with the error message:
error: overflow evaluating the requirement `uint::UInt<_, _> : private::PrivateCmp<uint::UInt<_, _>, Equal>` [E0275]
src/lib.rs:1:1: 1:1 note: consider adding a `#![recursion_limit="128"]` attribute to your crate
error: aborting due to previous error
It this expected? Perhaps this was bumping "close to the recursion limit" beforehand? I haven't diagnosed this much, but at least the reproduction is easy!
