Re: How do I determine number of matches in a regex?

Normally I'd be sorry for opening a can of worms, but this one was
informative enough that I'm glad I did. :-)

After thinking about it for a few minutes, I can't think of a
use for list() that doesn't just count elements.. so it does
seem like a rather useless addition.. and confusing too since
there really can't be an opposite to scalar().

Perhaps that should be added to the POD docs for scalar().  Until
it was pointed out to me, I didn't realise how little sense
the reverse was.  It should be obvious, but from the number of
times it gets talked about, it isn't.  You can upgrade a ship into a
fleey, but how do you turn a fleet into a ship?  (Other than sink
all but one of them:)
