Thanks for this feedback: I certainly would love to see us adopting a
workflow with regular reviews.  I'm glad to hear that you find hg
makes this natural and painless, since I think that regular patch
reviewing is something that will greatly increase the quality of the

I do have some questions:

- with major restructuring and writing wholesale new code, it seems
that waiting for reviews on everything might become a burden.  Does
sympy have enough active developers that this is never an issue for
you?  Do you always find someone to review a patch quickly?

- how do you deal with running from say 10 parallel repos day to day?
Do you keep changing symlinks to point to the active one, or do you
use setuptools 'develop' magic?
