I wanted to float the idea before spending time integrating things
into IPython.  I would wait for 0.11 for most of it. There are lots of
different pieces that should probably integrated at different times
and in different ways. The argparse stuff should probably be done with
the greater %refactor. There are some of my magics that should go into
Extensions, and maybe a few that should go into the main Magic.py;
integrating these before the %refactor would involve adding the
magic_arguments stuff in support, but explicitly "deprecated" for
external use. The terminal_size() utility could probably be added to
ipapi (hookble for GUIs to override, of course) immediately.

Which of my magics would you want for 0.10? and where (in Magic.py or
Extensions/)? I doubt it's worth holding up 0.10 if it's getting
