Thanks for pinging me on the PR, Paul. Both the original PR and the
addition of the context manager are great ideas.
Just to clarify, what I implemented in mpltools was a sort-of stylesheet
that can be easily accessed (i.e. you don't have to remember the path, just
the name; and if you forget that, it's listed in a module attribute). But,
I ended up using ConfigObj to parse the rc file instead of using
matplotlib's parser. One major disadvantage of that approach is that
ConfigObj uses a different syntax than matplotlib's rc parameters. In this
sense, the PR would help greatly to fix this discrepancy.
Unfortunately, the PR doesn't completely fulfill my needs. I wanted to
allow multiple stylesheets to be declared in a single file; this means I'd
need to plug into the loop that iterates over the lines of the file. I can
push in that direction on the PR, but I don't want to do that unless people
think this would be more-generally useful.
