digitalmars.D.learn - Function signature constraint syntax

Quick question: I have a function that takes an alias parameter:

	struct X { ... };

	void func(alias G)(object O) {
		...
		X x = ...;
		G(x);
		...
	}

How do I write a signature constraint that essentially specifies that G
should take a parameter of type X and return void?
