[PSyIR] Recognise array access in a Fortran executable statement #864

The Fortran2003 rule hierarchy does not distinguish between a scalar and an array assignment. Therefore the same rule hierarchy will be created in both cases. This means that it is up to fparser2reader to distinguish when creating PSyIR.

Is this still an issue @rupertford now that we support array assignments?

rupertford commented 2 years ago

I'm not sure. It could be about Fortran a = b + c where the variables may be scalars or arrays which I presume we simply pass through as a reference to the PSyIR at the moment.
