Thanks!  :-)

Indeed, "pypy --help" says "-O: dummy optimization flag for
compatibility with C Python".  Maybe it's a difference that we need to
fix at some point.  We never use "-O" ourselves, if only because you
can't translate pypy with this option --- the asserts in PyPy's own
source code are essential :-)

A bientôt,
