See the code below
$rboo = sub{($a,$b)=boo()};
$rzoo = sub{($a,$b)=zoo()};
$rhoo = sub{($a,$b)=hoo()};
print "return boo ", &$rboo, "\n" if (&$rboo);
print "return zoo ", &$rzoo, "\n" if (&$rzoo);
print "return hoo ", &$rhoo, "\n" if (&$rhoo);
sub boo {
return (1, 'bar');
}
sub zoo {
return (1, undef);
}
sub hoo {
return 0;
}
I'm not sure why it still print "return hoo". &$rhoo must evaluate to true... and I don't understand why?
Thanks,
