Are you saying that it's delusional to try and write portable code
that runs on POSIX-compliant platforms in Python?

Of course, any such attempt always has to be tested against the
platforms it's supposed to run on - after all, they may fail to
implement the standard correctly. But those are generally considered
to be bugs in the platform in question that need to be worked around,
*not* bugs in software. Since Apple is one of the few vendors
releasing products with a Unix certification, their products are prime
candidates as development platforms for anyone working on Unix
