Wrong-wrong-wrong! `wrap` is different, though with some
implementation similarities. First, it only works on polymorphic
types. Second, it actually creates a wrapper type while point of
typical `implements!(T, I)` is duck typing verification as-is in
templated code. It is basically a more generic form of
`isXXXRange`.
