It seems that,  for non elements,  __radd__ is set disfunctional
by the coercion model. On the other hand, it might be desirable
to have this enabled for people writing their own classes but having
reasons to avoid (parts of)  the coercion system (like me :-)

Might depend on #3738.

This could use a doctest. robertwb, do you want to write one, if not, I can probably do it a bit later.

Please go ahead and write one, though implementing __radd__ should not be encouraged.
