Using free functions and ADL can be dangerous since
there is always the chance of accidentally picking
up a function that means something totally different.

Traits don't have this limitation.  In some ways this
is like creating an adapter as you are doing.  The difference
is that the adaptation layer operates on any instance
of the adapted type rather than on one stored inside it.
