This commit is a response to feedback on the displayed type signatures results, by making generics act stricter. Generics are tightened by making order significant. This means `Vec<Allocator>` now matches only with a true vector of allocators, instead of matching the second type param. It also makes unboxing within generics stricter, so `Result<A, B>` only matches if `B` is in the error type and `A` is in the success type. The top level of the function search is unaffected.
