[Python-Dev] PEP 8 and optional underscores

[Guido van Rossum]

If you want to have a meaningful discussion about this, the addition
of the multiprocessing package and the recent threading.py API changes
must be rolled back, so we can design a proper API without the beta 1
pressure. Some observations:

- If it's isAlive() in Java style, it should be is_alive in Python style.

- I like *methods* (and functions) named isfoo or is_foo, but I like
the corresponding properties to be called just foo.

- I think properties instead of simple setters and getters is great
(as long as the setters implied in the property enforce the
conditions).

- I hate typing underscores, since they require using the shift key
*and* moving my hands away from the home position on the keybord.
