to give a working example of try/CATCH?

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

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

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.
So here's Perl 6 and it has

NP, it’s a good way for me to pick up the disparate Perl 6 clues

Hi Conrad,
It's only an issue of coordination and findability. But that question
depends on what the intended purpose of the wiki would be. For example
there is nothing stopping anyone (including members of this list) from

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