Subject: Is there a way to abandon a gsub if you're using a block?

I am using the form of gsub that takes a block to determine what to
substitute.

My problem is that I can't quite get the regex working, but I will be
able to detect that it matched incorrectly, once I can inspect the
backreferences in the block.

So: if I determine via code in the substitution block that I don't want
to do the substitution, is there a way to simply abandon the gsub call
on that particular iteration?

Wes
