[Python-Dev] Order of Fixers

At the moment, fixers are run in alphabetical order -- but this poses a problem, because some depend on others (for example, fix_print will need to be run _before_ fix_future, because fix_print looks for the 'from __future__ import ...' statement. I'm tempted to simply change fix_future to fix_zz_future... But that has some obvious drawbacks. Alternately, if future is the only dependent module, it might be marginally cleaner to simply special-case it in refactor.get_all_fix_names. So, any better suggestions?
