As for the map_iterator, then the interface has changed, so the adapters don't work. (the iterator supports .key() and * returns a reference to the value type, and not a pair) As for void_ptr_iterator, I guess it could be replaced with transform_iterator. I'm not sure if portability will suffer because of it, but I supsect it. I used operator.hpp to begin with, but moved awau due to portability reasons (vc6 stuff, I think). --Thorsten
