    [hippo]: Can anybody suggest a scalar value of $x for which ($x && !length $x) is true?
    [Corion]: hippo: If you have a Unicode-wise Perl then likely some zero-width characters in $x would work. Maybe $x = "\x{200b}" works.
    [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
