For some definition of natural: it makes sense once you see it, but is seem like most people expected something else (in our four person sample, only one person came up with this definition -- not that that's good statistics.). > > b. a**m = a**m.A broadcasting > > In languages that provide an answer, I have the impression > that the answer is usually (b).

It seems like it's likely to cause confusion and my impression is that it's not a common enough construction that having to use a function should be a big burden for most if not all people. -- . __ . |-\ . .
