Comment (by darij):
I'm not blaming your branch for slowing down tableaux! Actually, tableaux
are probably doing a good job at slowing down themselves, and there's been
a plan for quite a while now to rewrite their class hierarchy from
scratch. But I want to know what exactly it is that causes these slowdowns
in tableaux but nowhere else (kind of); that would probably an antipattern
we should try to avoid.
Are there good ways of finding out
1) what causes the slowdown, and
2) how the branches compare on more realistic measurements rather than
doctests (say, by dropping the cache between every doctest and the next
one?)?
