Really simple question:
how do I get the compiler-generated hash function for a given 
type?

For example:
Struct S
{
     int i;
}

can be used in an associative array. That means the compiler 
generates a "toHash" function. Is there any simple way to call it 
directly?

	struct S {
		int i;
	}

	void main() {
		auto s = S(123);
		import std.stdio;
		writeln(typeid(s).getHash(&s));
	}
