[pypy-dev] PyPy3: is bytecode really incompatible between releases?

No, my point was that if we want to do that we should first split the
usages, and only update the version used for C extension modules.  In
other words we should not update it for cffi modules (which is
unlikely to ever change, and I can check but I think the same .so
works for pypy2 and pypy3, so maybe a version number is not needed at
all); and also not for .pyc files (which should just be "pypy-36" for
pypy3 implementing python 3.6, and if at some point we really want to
add a new bytecode, then well, we'll think again, I suppose).


A bientôt,

Armin.
