You should not need "my" on the right side of a ->. Also, you should
be able to write $arg_for for constant subscripts.

Hi Everyone,
I never thought that my little script would get such loving

Open Question:
I realise I haven't kept up with every detail since the Perl6 RFC I
submitted way back in August 2000, but boy was I surprised to find,
now that I can actually use Perl6, it isn't just an improvement to
Perl (5), it's actually a "different language" (I'm quoting Michael

I think that is enough of a win on its own that mentioning any of the

Ah, perfect example Daniel. I know people say things like "Java is
better for big projects because of the strictness of it's typing". I
respond that Perl isn't intrinsically sloppy if you practice good
coding, it just doesn't straightjacket you into that all the time.

Thanks for that Ovid. I agree that any language must stand on it's
merits in the long-term, but there is an undeniable "hump" every new
language must get over to convince people it's worth trying in the
first place.

All error variables have been unified into $!, so it should show up there.
