There was a problem hiding this comment.
can you instead move that check to here?
a method called suggest_arbitrary_trait_bound should ideally do just that unconditionally

…dy, r=cjgillot Tidy up miscellaneous bounds suggestions Just some small fixes to suggestions - Generalizes `Ty::is_suggestable` into a `TypeVisitor`, so that it can be called on things other than `Ty` - Makes `impl Trait` in arg position no longer suggestible (generalizing the fix in rust-lang#97640) - Fixes `impl Trait` not being replaced with fresh type param when it's deeply nested in function signature (fixes rust-lang#97760) - Fixes some poor handling of `where` clauses with no predicates (also rust-lang#97760) - Uses `InferCtxt::resolve_numeric_literals_with_default` so we suggest `i32` instead of `{integer}` (fixes rust-lang#97677) Sorry there aren't many tests the fixes. Most of them would just be duplicates of other tests with empty `where` clauses or `impl Trait` in arg position instead of generic params. Let me know if you'd want more test coverage.
