Yup, I really like them.  Note that I also changed whos a little, to be more 
informative.  So now, upon startup, I get:

abdul[~]> ip --nobanner

In [1]: whos
Variable   Type                   Data/Info
db         IPython.macro.Macro    import 
mm         IPython.macro.Macro    for i in range(5):\n    i\n    \n\n34\n

db and mm are two macros I've got saved from debugging earlier today. 
Combined with %save and the ability to enter long, multi-line input with blank 
lines either directly or from copy/paste (this didn't use to work), I think 
ipython can be a useful little tool :)

Thanks again for your contributions: you've made a real difference in some of 
these really useful areas.
