I think the main issue will be any changes from Mailman 2's "Handler"
API to Mailman 3's "Handler" (message-altering) and "Rule"
(non-mutating) APIs, and how to communicate between them if both rules
and handlers are used.

Of course you're also welcome to do algorithmic and style cleanups
(the original from_is_list implementation was submitted by a third
party and we were in a hurry to do something so the style is suspect
-- I admit haven't looked at it, but somebody[tm] should :-).
