…ture. When lowering closures, we avoid capturing the enclosing generic context when possible. However, the generic context may still be necessary to canonicalize types mentioned inside the closure, such as when an associated type is referred to that is same-typed to a concrete type.

Explanation: When a closure referred to a type parameter in a context where the parameter was same-type-constrained to a concrete type, the compiler would crash.
Scope: Fallout from allowing same-type constraints on concrete type extensions. Where we used to raise compiler errors, we would now crash.
