The issue is clear I think. How about we undo this change, agree not to use
things like the inspect module unless absolutely necessary, and catch this
in review next time?
It would be good though if some people could still look at the minimize()
API. Right now it hasn't been released yet, so we can make any change that
would make it simpler/cleaner.
