Ah, indeed.

Perhaps the first couple times the user will have to look up the type definition (which isn't hard since it will be in the same code block). But subsequently the user will read, e.g., "WrapperFunction<Type>" and just know what's expected, instead of having to mentally reparse the long parameter type every time.
