you're right, it wasn't that, I was trying to locally override a regex 
object as follows:

re_somepattern = re.compile('abc')
re_someotherpattern = re.compile('def')

def func():
    if somecondition:
        re_somepattern = re_someotherpattern

    <code block>
        re_somepattern.match('something')
    </code.block>

not sure how to override this the way I want, it'd be quite messy if I 
had to do huge if blocks to handle this inside the other code blocks 
that use this re_somepattern.match()

or perhaps I'm going about this all wrong....
