[New-bugs-announce] [issue22817] re.split fails with lookahead/behind

[Rex Dwyer]

New submission from Rex Dwyer:

I would like to split a DNA sequence with a restriction enzyme.
A description enzyme can be describe as, e.g.  r'(?<CA)(?=GCTG)'
I cannot get re.split to split on this pattern as perl 5 does.
