Note that this is a "classic" Fortran compiler optimization, you can verify that at least all of gfortran, ifx, and nvfortran are doing it on something very easy like:

```
subroutine test
interface
 function foo()
    real :: foo(100)
 end function
end interface
   real x(100)
   x = foo()
   call bar(x)
end subroutine
```
