in thread Perl oddities

system returning true on failure, false on success. I know why it's doing that, I know where it's coming from (and that's why), but it still makes me gag each and every time I use it.

I think Larry realises this. I'm hoping that Perl6's system function knows to do something like return $rc but ! $rc. Then 0 would be true and non-zero would be false, when checked in boolean context, but the return code would still be available:

my $rc = system(...); unless ($rc) { print "system failed with rc = $rc!\n"; }
(Or something like that - my perl6 isn't rusty, it's just not there yet ;->)
