Nnngg. I'm not keen on Python ever gaining privacy (the __ name mangling is
nasty, I agree). It just doesn't really seem in the spirit of things; I
always tend to think of the Larry Wall quote "Perl would rather you kept out
of its living room because you weren't invited, not because it has a
shotgun".
In my recent projects, I denote "private" (there's no distinction between
private, protected etc as there is in, say, Java) by just preceeding names
with a "_". I've actually found that highly effective, and it makes it
obvious that "self._method()" and so on are private calls. This approach
also tends to make modules fairly "from module import *" safe.
The only argument I can imagine for privacy is that "from module import *"
tends to import module names etc as well which can make it confusing; but
when we use that feature we deserve everything we get <wink>.
