Summary: problems with re.py and regex.py

Details: Hi, here is something I have been working on for quite some time. I always thought it was my regex syntax, but I was incorrect. I tried it in perl, and php, and both worked fine.

re.py has a problem with ([_a-zA-Z0-9-]\.*) where it hangs during compilation.
regex.py has a problem with ([a-zA-Z]){2,3} (or any other similar statement) where it does not limit the number of characters properly.

Here is the code
...
import string
import sys
import regex

def testemailaddr(emailaddr):
	pattern = regex.compile('^([_a-zA-Z0-9-]\.*){3,255}@([_a-zA-Z0-9-]\.*){3,255}\.([a-zA-Z]){2,3}$')
	if pattern.match(emailaddr) != None:
		valid = [1, emailaddr]
	else:
		valid = [0, emailaddr]
	return valid

validemail = testemailaddr(sys.argv[1])
if validemail[0] == 1: print validemail[1], "is valid."
else: print validemail[1], "is not valid."
