You are right... I don't know why I thought there was math here... It's
not in sys.modules either...
Is there "a place" where you can find a list of 'some' available modules
('standard' ones like math, sys, ...) but not all, or I really need a
break during the week-end?
If so, what the difference between the 'present' and the 'missing' ones?
For example, in http://docs.python.org/modindex.html for math: "This
module is always available." unlike pickle or HTMLParser. Is this only
because of the versions of Python?
I think I have mixed-up a lot of things and that I need a little bit
more of readings about builtin things... (Doc that goes further than
http://docs.python.org/lib/builtin.html)

At least I have learn a new module =)

Ok. Should I only see `__builtins__` as an access to builtin
functions/exception/... ?

Fair enough ^_^

I think the answer is that I need more rest...
