1. [New issue] introduce support for readline module (raw input)
http://ironpython.codeplex.com/workitem/33164
User paweljasinski has proposed the issue:

"This is to track changes required to (re) introduce support for readline module.
There is a relevant item which probably could be closed: http://ironpython.codeplex.com/workitem/697

As long as it works without readline, and it's not *too* terrible of a
hack, that should be fine. There are a few modules (zipimport comes to
mind) that slot into CPython in weird ways, and we might be stuck with
them.

It might be interesting to use some of the functionality in
SuperConsole to implement history w/o readline, but I imagine
readline's specific details (C-r, C-e, C-a, etc.) are wired into a lot
of people's fingers, and so having the actual readline available is
probably a good idea.

All the more reason to fix the packaging story for IronPython so that
readline can be easily distributed."
