Had a similar experience recently. Class A had some code that would be
very handy in class B. I thought the code in question would probably
work unchanged, since A and B already contained all the data attributes
needed. So I pulled the method in question (only -- the data on which it
depended stayed put) out into a separate mixin class, had A and B
inherit
the new class, and Poof! It worked immediately. I used to be a
static-analysis zealot, but I am gaining a really strong appreciation
for Python's wonderful dynamicism.
