Thanks for asking :-)  I'm fine with staying out of language design
issues like this one, and I believe it's the general concensus in
PyPy.  Whatever gets decided will probably be easy to port to PyPy and
have no measurable performance impact: the extra checks on the type,
if any, are all constant-folded by the JIT.

A bientôt,
