Subject: Regular expression object question

Hi all,

Is there a way to add a new regex to an existing regular expression 
object?

In other words, say I start with a pattern I want to match:

re = /xyz/

But later, I decide that I want to also match "abc".  As it stands now, 
I have to create a new regex object for that.  Thus:

re2 = /abc/

This could go on indefinitely, so simply doing this could quickly become 
cumbersome:

if re.match(string) || re2.match(string)...

Thus, what I would like is a way to "push" a new regex onto an old one 
(i.e. add an "and" or "or").

example:

re = /xyz/
re.push("|abc") -> re is now /xyz|abc/

Thoughts?  Should I just create my own subclass that does this and shut 
up?

Regards,

Dan
