FunctionCall works with Sum not Product

Not sure if it is my coding or the capability of CL.

I can use functionCall with patterns.sum or patterns.difference, but not with patterns.product.

I can’t help you, sorry, but I’m interested to understand more about what functionCall actually is/does? I can’t find it documented anywhere…

It was described in the May newsletter. Are you subscribed to that?

No, I’m not - I usually access them through the archives but just assumed there hadn’t been one since March…

Guess I ought to actually subscribe, then!
