Re: [patch, fortran] Handling of .and. and .or. expressions

If the semantic model is unclear on whether a function with potential

I disagree here, strongly. We are talking Fortran, and not C (where
everything is a function, and often the whole point of calling a
function is its side effects).

And we are not going to change Fortran semantics. And I also oppose
defining our own subset of Fortran in the hope that people will make
fewer mistakes.

A function is something that produces a value.  If the value is not
needed to produce the correct result, the function need not be called.
