Sounds to me like you want some sort of AST transform, possibly in an
import hook. Check out something like MacroPy for an idea of how
powerful this sort of thing can be.

Hi,
following up on this thread on StackOverflow
http://stackoverflow.com/questions/16515347/python-import-hooks-and-main
does somebody has a great idea how to manage this?
The issue at hand is, that I would like to apply a specific import hook
right from the beginning of the interpreter run

Hey Victor,
for proper parsing into native Python types, I would recommend YAML.
Also also supports (besides int vs. float) dates and datetimes.
Cheers,

I agree as well. First evaluate the right side, then assign it to the
left side at once.

I agree with Skybuck Flying.
I am aware if a var is a module function var or a module global var.

It is the good idea of Python about modules which are singletons

Hi folks,
currently, I came across http://pythonwheels.com/ during researching how
to make a proper Python distribution for PyPI. I thought it would be
great idea to tell other maintainers to upload their content as wheels
