So did the approach in the post I was replying to -- there was a list
of pairs, each made up of an identifier and a compiled re object, and
the code was elsewhere. Personally I like this approach, which is why
I accepted it as posted and built on it -- so I don't see why you're
claiming that this is a differentiator between Alexander's aproach
and mine.

It's one case, but it's very far from being the only one.

Why doesn't it? Alexander's post to which I was replying had no
groups at all in the regex patterns -- are you claiming he was
utterly missing the point of the thread, and his example totally
irrelevant?
