"A++++++++ great seller would buy again" on the llama bit. It rocks.

porpoises entertain red lobsters? see, I'm bad at this.

penguins envy running lemmings? nope, not good either.

puppies eat random legos! YES! victory.

    [Corion]: Hmm - no, that outputs 1 for me on 5.14 - perl -wle "my $x = qq(\x{200b}); warn $x; warn length $x"
    [hippo]: Smart - I'll give that a go. Thanks.
    [hippo]: Ah
    [Corion]: But maybe there is some other Unicode string that will be true but have a zero width
    [hippo]: For explanation, I've seen this construct in someone else's code (no names, no pack drill) and couldn't think of a situation to trigger it.
    [Corion]: You'll have to look somewhere esoteric for that. Maybe some tied variable or special dualvar can also trigger that. But it's certainly not a common occurrence
    [Corion]: And on 5.20, the following also outputs no find:perl -wle 'for my $x ("\x{2000}".."\ x{1fffff}") { if( $x && ! length $x ) { warn qq(<$x>); warn length $x; die } }'
    [Corion]: (this time on Unix)
    [hippo]: Understood. I'll have to go through the code and see if it's doing anything fancy with ties, dual-vars or non-scalars. In the end, it's probably a bug though.
