Ah, thanks Daniel. Therefore the situation is becoming more clear.

Then - assuming this interpretation is correct - I'm not sure what we want to
do from a practical point of view: should we arrange the front-end to always
have the static_assertion triggered (thus, even without -pedantic) or we really
want that only when -pedantic is passed? I'm not clear whether the user may
like to see the value is std::is_assignable changing depending on -pedantic?!?
I never pondered that possibility in the past.

I guess Jason should give a direction, here.
