certain
regular expressions

Priority: major | Milestone: sage-4.0.2
Component: interfaces | Keywords: gap interface expect regular expression

Comment(by SimonKing):
Concerning the timings, one cautious remark:
I ''did'' have the good timing with my patch. But later, I tried again,
and it was not as good (though still faster than without the patch).

Perhaps someone can explain why this happens. It seems that this is a bad
benchmark test.
So, I would appreciate a better (more stable) example.
