make_insertion() rather than specify each std::stl container.

It's only on vc6 that each header is included; normal compilers can do much
better.

I think there is a way to do this without including each header, but it
probably won't work with many compilers. So it all depends on a
portable hack that can detect member functions or member typedefs of certain
names.

Maybe. Why do you think its better with a traits class compared to a ADL of
a user-overloaded function?
