[issue2537] re.compile(r'((x|y+)*)*') should fail

[Matthew Barnett]

Matthew Barnett <python at mrabarnett.plus.com> added the comment:

The re module is addressed in issue #2636.

BTW, my regex module behaves like Ruby:

>>> regex.sub(r"((x|y)*)*", "(\\1, \\2)", "xyyzy", count=1)
'(, y)zy'
>>> regex.sub(r"((x|y+)*)*", "(\\1, \\2)", "xyyzy", count=1)
'(, yy)zy'
