Question: Consider an expression like a + b that is passed to a subroutine in Fortran. Is there any semantically meaningful difference between passing this expression

Consider an expression like a + b that is passed to a subroutine in Fortran. Is there any semantically meaningful difference between passing this expression as a reference to an unnamed temporary (as Fortran does) or passing it by value (as one might, for example, in Pascal)? That is, can the programmer tell the difference between a parameter that is a value and a parameter that is a reference to a temporary?
