I don't believe that's true, because this is the syntax he showed:

I guess I still don't really understand what he's getting at or what the
value of @callmeta is in that example. It just seems like extra noise with
no value to me...

Ron: what *precisely* does the @callmeta decorator do? If you can express it
in code, so much the better.
