Description

Apparently this is expected to fail:

import re

# this works
re.compile('^(?:a|b|c|d|e|f|g|h|i|j|k|l|m|n|o|p|q|r|s|t|u|v)$')

# this fails
re.compile('^(?:a|b|c|d|e|f|g|h|i|j|k|l|m|n|o|p|q|r|s|t|u|v|w)$')

but at least the error could hint that's because there are too many operations to handle, instead of:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: error in regex

'cause there is no error, strictly speaking, in that regex, it's a hard (default) limitation on MicroPython side.

Thanks.
