Indeed... although IBAction isn't so bad as a mixin, it gets much worse 
with ObjcMethod where it is necessary to list all the argument types to 
allow resolving overloaded functions:

	void doOneAndTwo(int i, int j) {}

	mixin ObjcMethod(void, doOneAndTwo, "doOne:andTwo:", int, int);

Compare to what could be done with a parametrized attribute:

	@ObjcMethod("doOne:andTwo:") void doOneAndTwo(int i, int j);

That'd would be a lot more convenient, especially with interfaces for 
which none of the mixin above can work (they insert some static struct 
member to store the "attributes").
