I expected the code to compile without errors. Instead, I got the following compile error:
Compiling playground v0.0.1 (/playground)
error: implementation of `FnOnce` is not general enough
--> src/lib.rs:4:5

4 | foo()
| ^^^^^ implementation of `FnOnce` is not general enough

= note: closure with signature `fn(&'0 ()) -> {async block@src/lib.rs:10:46: 10:54}` must implement `FnOnce<(&'1 (),)>`, for any two lifetimes `'0` and `'1`...
= note: ...but it actually implements `FnOnce<(&(),)>`
error: could not compile `playground` (lib) due to 1 previous error
Possibly related to #126044
See also #126550, which has similar reproduction code.

Tested on the playground with stable (1.79.0) and nightly (1.81.0-nightly (2024-06-15 3cf924b934322fd7b514))
