Re: [boost] intrusive_ptr and overloading not working under VC++ 8

doesnt work because of A, that has nothing to do with A...

IMHO, being able to do this is a must.

This is useful functionality, but the suggested "trivial implementation" breaks shared_ptr/intrusive_ptr on all legacy compilers (easy to fix) and carries the cost of including a type traits header (possible to fix if someone cares to find the time to do it). Note also that the above code is not required to work with tr1::shared_ptr (not so easy to fix :-) ).
