Hmm - it appears to work with either construct, but as you say, it's
obviously incorrect to rely on this. I had assumed that the only reason
you have to use 'in' is when you will be using the result of a previous
calculation.

So I've also fixed this (potential) bug.

Using classic divide and conquer I managed to track down the thread bug
to an incorrect Field(x,y) macro earlier in the initialisation.

Thanks for all the help
