Description Christopher Head 2009-09-21 02:52:25 UTC 
It would be useful and appropriate if RefPtr implemented operator->*(), just as it implements operator->(). Then you could dereference a pointer to a member of a class against a RefPtr to an object of that class.
Comment 1 Christopher Head 2010-02-08 07:32:24 UTC 
OK, apparently operator->* is rather horrific to implement, seeing as it's not just a simple matter of returning the underlying object. Instead, how about providing a nicer way of getting the underlying raw pointer (or even just a reference to the underlying object), so that the built-in ->* or .* can be used? Right now I have to do this:

(ptr.operator->()->*fptr)();

which is pretty ugly. This would be nicer:

(ptr.get()->*fptr)();

but requires the addition of a get() function.
