This was present in fortran-vars' evaluator. Currently, all arguments for functions and operators are eagerly evaluated. (I picked this because it was easier to write, since I couldn't find any relevant standards/expectations for compilers.) It would be straightforward to add a switch for selecting between short-circuit and eager-evaluation.

This was present in fortran-vars' evaluator. Currently, all arguments for functions and operators are eagerly evaluated. (I picked this because it was easier to write, since I couldn't find any relevant standards/expectations for compilers.) It would be straightforward to add a switch for selecting between short-circuit and eager-evaluation.

We would add the switch by extending the evaluator monad to include some Reader environment -- this was always the plan, we simply didn't have any config yet. Then the binary operator and function call evaluation code would be changed to inspect the current mode and provide the appropriate behaviour.
