Pugs prints five zeros, so it looks like Perl 6 (or at least the Pugs
variant) will get rid of that obscenity at least partially (it still
didn't complain that $var was not declared). However, given this
code:
#!/usr/bin/pugs
{
my $i;
sub iter {
return $i++;
}
}
say iter() for 1 .. 5;
say $i; #$i should not be in scope
pugs says
0
