Note on PEP 299

[bearophileHUGS]

I don't like much the syntax of:
if __name__ == '__main__':

Some time ago I have read this PEP:
http://www.python.org/dev/peps/pep-0299/

And why it was refused:
http://mail.python.org/pipermail/python-dev/2006-March/062955.html

I think the name of the standard main function may be just main(), so
there isn't the problem with the import (and *maybe* the problem with
multiple Python versions can be ignored with Python 3.0).

If a module contains the main(), the main() is executed when the module
is run alone. Otherwise you can import the module, with the main()
function managed as a normal function.

This idea, and a couple of variations, have come up in the Py3 discussions,
so something might be tried.

turns
if __name__ == '__main__': sys.exit(main(sys.argv))
into
import mainer

It's a bit of magic, I'll test it more, but it seems to work binding
the main() with Psyco too.
I have changed it a little (removed argv passed to the main and the
import of type, etc).
I don't know if/when I'll use it, but it seems nice enough.

Bye,
thank you,
