The following changes to shared_ptr might still be controversial:

// Namespace std:: definitions removed (Peter Dimov)
//
// Rationale:
//
// std::swap() overloads are illegal (17.4.3.1/1, LWG issue #226)
//
// std::less<> specializations that do not call operator< are illegal
//   (17.4.3.1/1, 20.3.3/5)
//
// std::less cannot be partially specialized on compilers that do not
//   support the feature
//
// std::less specializations do not help in cases like
//   map<pair<shared_ptr, int>, int>

I'm too tired of the whole problem to have a strong opinion any
more, and having shared_ptr::operator< doesn't seem nearly
as evil as the core and library issues that specializing std::less
stumbles into.
