// Regression test for #81522.
// Ensures that `#[allow(unstable_name_collisions)]` appended to things other than function
// suppresses the corresponding diagnostics emitted from inside them.
// But note that this attribute doesn't work for macro invocations if it is appended directly.

// aux-build:inference_unstable_iterator.rs
// aux-build:inference_unstable_itertools.rs
