Summary: Make Generators Pickle-able

Initial Comment:
Would it be possible to make generators pickle-able?  I
mean, currently the internal state is saved in some
way.  Would it be possible to make pickle handle them?

Put another way, if generators had a __getnewargs__
function that returned some data (say a tuple of module
name, function name, locals/globals dicts and some code
dependent location data) and then allow:

  generator.__new__(statedata)

to reconstruct it (or something more elegant).

Moving into the feature requests tracker.

I don't think this is possible (or should be done if it were
possible). Pickle has traditionally abstained from pickling
functions, so IMO it should not picke generators, either. If
this was enabled by default, it would open up yet another
security hole.
