Description
Code
I tried this code: https://github.com/Smithay/calloop/tree/v0.4.4 cargo check
I expected to see this happen: successful build
Instead, this happened: build fails on the new beta (1.63)
error: implementation of `ErasedIdle` is not general enough
--> src/loop_logic.rs:96:16

96 | Idle { callback }
| ^^^^^^^^ implementation of `ErasedIdle` is not general enough

= note: `ErasedIdle` would have to be implemented for the type `Option<Box<dyn for<'r> FnMut(&'r mut Data)>>`
= note: ...but `ErasedIdle` is actually implemented for the type `Option<Box<(dyn FnMut(&'0 mut Data) + 'static)>>`, for some specific lifetime `'0`
