[New-bugs-announce] [issue22437] re module: number of named groups is limited to 100 max

[Yury Selivanov]

New submission from Yury Selivanov:

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, so I'm not sure if this check can be lifted, or at least if the number can be bumped to 200 or 500 (why is 100 btw?)

Please share your thoughts.
