Yes, it is possible to build full property table for bytes regexps at regexp
compile time. But it is impossible for unicode regexps (issue22407). And in any
case this doesn't solve original problem: re.match(pattern, string, re.L|re.I)
can return unexpected

When you lookup the pattern in the cache, include the current locale as part of

Here is a patch which implements Matthew's suggestion. It significant slow down

@Serhiy: You're overlooking that the LOCALE flag could be inline, e.g.
r'(?L)\w+'.
Basically, if you've seen the pattern before, you know whether it has an inline
LOCALE flag; if you haven't seen the pattern before, you'll need to parse it
anyway, and then
New submission from R. David Murray:
https://docs.python.org/3/library/logging.html#logging.Logger.getEffectiveLevel
This says the logging level is returned, but it doesn't mention that what is
returned is an integer, nor does it link to whatever method is needed to
convert the integer return
Demian Brecht added the comment:
Antoine: On (finally) getting back to this and re-reading your test case, the
current behaviour is incorrect and is corrected by the patch. I've added a few
more test cases to ensure trailing slashes are handled correctly.

Answering Guido's question about the Enum class. No, it is not appropriate
here. It has too cumbersome repr (OPCODES.IN_IGNORE: 16 instead of
IN_IGNORE). Enum function syntax can't by used because it enumerates values
from 1. We need three Enum subclasses

While writing a lexer for javascript language, I managed to hit the limit of
named groups in one regexp, it's 100. The check is in sre_compile.py:compile()
function, and there is even an XXX comment on this.
Unfortunately, I'm not an expert in this module,
R. David Murray added the comment:
Ah, yes, I was just being dense, because the context I was in was exactly that
context: configuration via strings. Probably no change is required, but if can
think of way of making it obvious to someone thinking crooked like I was that
would be great.

Woops, should have looked at the rest of my email. Yes, that change looks

It is 100 to avoid a syntactic ambiguity between numbered groups and octal
numbers, if I remember correctly. I can't remember if that constraint still
applies in python3, where the octal notation was made more strict in general.

I think you are too casual in rejecting a standard approach over a custom
clever hack. Making the values enums gives them a standard interface that
goes beyond what you implemented, and just the fact that we can say these
are IntEnum instances specifies a lot

In the regex module, I borrowed the \g... escape from .sub's replacement
