Re: [boost] [shared_ptr] Why operator< uses internal_less?

I see that operator== and operator!= are implemented comparing the pointer inside the shared_ptr's using get(), but operator< uses _internal_less, that does a different thing.

I thought that operator< would also be implemented using get(), so please, can you share the rationale behind the need for _internal_less?

get() returns px (the raw pointer), _internal_less compares pn (the shared_count). This is peculiar, since it means that alias pointers to different subobjects would compare non-equal, but sort equivalent. I'd like to know the rationale of this, too. Sebastian
