For what it's worth, I like the idea of pushing namespaces.  With the
current system, you can do (as a random example)

  push(*_ip.user_ns)

but then you have to make sure that the dict doesn't contain some
special keywords.  I imagine it would be better to shield the user
from such unexpected side-effects.
