Another point on this.  Since we use straight python instead of a custom 
string-based syntax, we can do:

k=4
%timeit(runs=k) 2+3

or

%timeit(setup="x=%s"%random.random())
x+4

Using straight python instead of a custom string-based file format is 
something I learned from IPython when you guys made your config files 
actually just python files.  I find it somewhat ironic now that you are 
arguing against making something more pythonic, and implicitly rejecting 
the programmability and power of having a pythonic syntax :).

Thanks,

Jason
