Ahh, I didn't notice that at all, I was wondering why it was complaining
about it...shoulda twigged :)

Hmm, I do like that notation.

OK, I had tried
my @bar = @{ shift };
but that doesn't work. I'll start using shift() I think, as that looks
best to me.

I may avoid this one, it looks like it is too easy to get in trouble
with...:)

I tried this, but for some reason it didn't do what I wanted. I may have
just done it wrong I guess.
As for the method Roberto mentioned, of dereferencing later on, I had
thought about that, but found it too verbose.
Thanks for the help!
