// With the current compiler logic, we cannot have both the `112225-1` case,
|
||
|
|
// and this `112225-2` case working, as the type inference depends on the evaluation
|
||
|
|
// order, and there is some explicit ordering going on.
|
||
|
|
// See the `check_closures` part in `FnCtxt::check_argument_types`.
|
||
|
|
// The `112225-1` case was a regression in real world code, whereas the `112225-2`
|
||
|
|
// case never used to work prior to 1.70.
