I'm in favor of this, too.  There's a good amount of code written by myself that does not comply but has not gotten changed because I didn't want to break old scripts.  I wouldn't mind fixing it all as a part of one big effort.

I am broadly in favor of using PEP-8 standards.  (As long as we're on
the topic, Kacper also had a great suggestion that we run static
analysis like pyflakes.)  Our oldest open ticket, from pre-BB
migration, is about PEP-8.

https://bitbucket.org/yt_analysis/yt/issue/39/follow-pep8-style-conventions

Fixing line length and so on I am fine with being done automatically
with one of those tools.  For changing method names, which I am also
in favor of, we should either identify them and fix them manually or
use a refactoring tool like rope or bicycle repair man.

For all of this I would like to do it in one go, with a single bandaid
to rip off, and beforehand consolidate all extant branches.  RIght now
we have a couple things under active development; we could do this
relatively soon, but I think we need some kind of coordinated effort
to merge relatively quickly back into those branches to make sure we
don't just cause a ton of merge conflicts.  Here's my proposal:

 * Make the change to main branch
 * Merge those into geometry, rockstar, volume rendering
 * Add pyflakes and/or pep8 checks to Jenkins

Thoughts?
