Just read further back through the thread and looks like Monte has a handle
on it

I’ve taken a little look into it and yes it does appear the chunk is being
> evaluated twice: Add left to right
> - get value to add by and evaluate chunk if any
> - get destination value and evaluate chunk if any
> - add
> - set destination value and evaluate chunk if any So I think we can both
> fix this quirk and optimise things that mutate rather than replace the
> destination chunk (add, subtract, multiply, divide commands… are there
> others?) by setting the previously marked chunk rather than re-evaluating.
> Please submit a bug report so we can look into it further and work out
> whether I’m right or I just don’t know my way around the engine well enough
> yet ;-) Cheers Monte
