he considered "0" to be false, That's not quite the same things as considering '00' to be non-zero is it! `C:\test>perl -e"print '00' == 0" 1` [download] Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

That's not quite the same things as considering '00' to be non-zero is it! No, but you were complaining about the arbitraryness. It has the same arbitraryness as for true/false. `C:\test>perl -e"print '00' == 0" 1` [download] So what? `$ perl -E 'say "BrowserUK" == 0' 1 $ perl -E 'say "00" eq 0' $` [download] Heh, I made the challenge, I make the rules. If you don't like the rules, don't play.	[reply] [d/l] [select]

Certainly is interesting that quoted 00 is true while quoted 0 is false (but it sounds like '0', "0" are special cases). `perl -E 'say 0 ? q{true} : q{false}' # false perl -E 'say 00 ? q{true} : q{false}' # false perl -E 'say q{0} ? q{true} : q{false}' # false perl -E 'say qq{0} ? q{true} : q{false}' # false perl -E 'say q{00} ? q{true} : q{false}' # true perl -E 'say qq{00} ? q{true} : q{false}' # true` [download] Perl 5.10.1 on Solaris 10 SPARC.
