For me it makes not much difference
whether traits or a class helper is used,
as long as it is a working solution.

A class helper, however, needs partial specialization,
which is, AFAIK, not so well supported on some compilers

From a pragmatic point of view,
I would like to see a solution that works
on as many compilers as possible.

Are there any experiences what to prefer?
