Given these functions:

	int func1(string x, int[] y);
	int func2(string x, int[] y...);

Is there a way to tell, using compile-time introspection, the difference between their signatures?

Using std.traits.Parameters shows both functions as having signature
(string, int[]).

typeof(&func2).stringof does show the `...` but I'd rather not rely on parsing .stringof if at all possible.

Maybe this?  https://dlang.org/phobos/std_traits.html#variadicFunctionStyle
