Kay Schluehr replied to my question:
Why do you want to use a regex for this?
Because it is part of a tokenizer that already uses regexps and I do
not intend to rewrite / replace it.
Switching to pytst is not a big change - there will be little
impact on the rest of your code. On the other

Yes. But I left there nearly a decade ago.

Mirco,
with special characters I mentioned control characters of regular
expressions i.e. one of .^$()?[]{}\|+* but not non ascii-127
characters.
For a workaround you simply have to mangle those using an escape
control character:
REGEXCHAR = .^$()?[]{}\\|+*
def mangle(s):
pattern = []

Why do you want to use a regex for this? When you have constant
strings

It uses Aho-Corasick for the implementation which is fast and does what
you expect it to do. Nor does it have a problem of matching more than
99 possible strings as the regexp approach may have.

Given that Python's re engine doesn't support this feature
it doesn't really help the original poster's problem.
Even if some future Python did support it, the limit

with reverse sorting as in your proposal.The naive solution is easy to
generate but I'm sceptical about its cost effectiveness. On the other
hand I do not want to investigate this matter if somebody else already
did it thoroughly.
