That's not true, though. The default Compare template parameter will work if
the compiler supports partial specialization, because the less<shared_ptr>
is a specialization of std::less.

The functor that is supplied is a specialization of std::less and would only
have to be passed explicitly in the case of a compiler or library that is
broken.

I think you should reword what you added.
