I try to keep ipython 2.2-compatible, though to be honest I haven't actually 
_checked_ with 2.2 in a long time.  My default python runtime is 2.3, and 
there are still a lot of 2.3 installations out there.  I think it would be 
nice to keep 2.3 compatibility, but if it becomes a real burden, it's OK to go 
for 2.4 (I have it installed as well).  By the time this code becomes really 
stable and widely usable, 2.4 will have been out for long enough that it will 
be reasonable to use it as a baseline.

In summary, if @decorators and such really are helping the readability and 
clarity of the code, keep 2.4.  I'll adapt.
