Regarding -O, it would also be nice to have a higher-level way to find
out what optimization level the current interpreter is running under.
Currently, as I understand it, there's no way to predict whether
py_compile will generate .pyc or .pyo files, which is a minor annoyance
in the Distutils installation code. However, if Jim's mythical sys
variable is guaranteed to canonicalize Python's command-line options so
that something like
"-O" in sys.python_argv
would always answer this question, I'd be satisfied.
