In addition, it occurred to me this evening that there's functionality in
the csv module I don't think anybody uses.  For example, you can register
CSV dialects by name, then pass in the string name instead of the dialect
class.  I'd be in favor of scrapping list_dialects, register_dialect and
unregister_dialect altogether.  While they are probably trivial little
functions I don't think they add much if anything to the implementation and
just complicate the _csv extension module slightly.  I'm also not aware that
anyone really uses the Sniffer class, though it does provide some useful
functionality should you need to analyze random CSV files.
