I agree with what I think your assessment is. That is: foo->@*[0] is not
@foo[0]. ->&() is not needed. ->*{foo}, I'm not sure. I think it may be
needed to get a purely-postfix entry out of a typeglob reference, but it's
something I've done so rarely that I'm not sure and I am writing this message
as I walk out the door. I'd rather hit send than test.
If nothing else, it can wait!

I am excited to test it. Hopefully tomorrow, more likely Tuesday.
Thanks, though!
