I haven't tested this either, by the way, but it looks reasonable.
The only problem I can see in the above is an operator precedence
error.

You will need parenthesis around the code to the right of the *, so
it's "quantity * (...whichever weight...)".

Oh, and [calcn] will be more efficient than [perl] for the above.  As
it's a one-shot operation, it probably won't make too much difference
and, as you said, it was only an example.
