in reply to comparing two values under 'perl -w'

Shouldnt use $a and $b as they can have bizzare side. And i have no idea if this is more or less elegant than yours... (IMO its easier to understand, but then again I like ternary ops.) 
my $equal=defined($x) && defined($y) ? $x==$y : !defined($x) && !defin
+ed($y) ? 1 : 0;
