"0 but true" is the only special case (
http://perl5.git.perl.org/perl.git/blob/da1010ecc50c91387eed9bcc349e6960909a3484:/numeric.c#l747),
but there are many ways of writing zero other than "0".
http://www.perlmonks.org/?node_id=464548 has quite a few.

There's been a regression since that node was written. The following used to
be silent.

$ perl -wle'print 0+"0x0"'
Argument "0x0" isn't numeric in addition (+) at -e line 1.
0
