[New-bugs-announce] [issue38660] Checking if two regexes are equal should test if they are functionally equivalent

[Борис Верховский]

New submission from Борис Верховский <boris.verk at gmail.com>:

re.compile('([-_.a-zA-Z0-9]+)') == re.compile(r'([-\w.]+)') 

should return True because those are the same regex (\w is a-z, A-Z, 0-9 and the underscore). 

If you want to check if two regexes are identical you would compare the original strings, before re.compile.
