Ville is already aware of this, but just so you can make his work a little 
easier, please use non-decorator syntax on all code that we can include in 
shipping IPython.  We still need to support python 2.3 users, and decorators 
can be written (admittedly less elegantly) as regular function calls.

Yup.  Not the nicest, but it works.  This can also be written as:

try:
   __IPYTHON__
   ipython_on = True
except NameError:
   ipython_on = False

It's pretty much up to you.  Ville may have added a wrapper to this in the new 
api module, I'm not sure.

Nice.  I look forward to playing with this, now that I don't have to write it :)

Cheers,
