Finalize GC memory

[Namespace]

Here my new version:
----
void Delete(T)(ref T var) if (isAssignable!(T, typeof(null)) && 
!isStaticArray!T) {
	const bool isPtr = is(T : U*, U);

	static if (isPtr && (is(U == struct) || is(U == class)))
		.destroy(*var);

	static if (is(T : U[], U))
		GC.free(var.ptr);
	else {
		static if (isPtr)
			GC.free(var);
		else
			GC.free(&var);
	}

	var = null;
}
----

That should fulfill all wishes. :)
