There's a couple of things That smell bad to me about this. They're personal things; I don't have any doubts that the code works. It's just things that trouble me:

• a block pretending to be a loop, and the use of redo and last therein.
• (this is definatley just me) chomp that isn't the first thing done in the "loop". I'd have put it first, even if any subsequent print (etc) had to include \n.

I'd be happier with a do block, rather than a bare block. Perhaps it's just me :)

Like I said, personal things.

update: added stuff about do after further thought
