On second thought, that won't work. Concept check causes a compilation
error when the argument does not conform to the concept.
Perhaps you can do it the other way around? Check for a T::begin member
function to see if the type is a container, and assume the type is an
iterator in the default case? I'm not sure what that check would look
like though.
