//! This test shows a situation where through subtle compiler changes we can
|
|
//! suddenly infer a different lifetime in the hidden type, and thus not meet
|
|
//! the opaque type bounds anymore. In this case `'a` and `'b` are equal, so
|
|
//! picking either is fine, but then we'll fail an identity check of the hidden
|
|
//! type and the expected hidden type.
