The following program is invalid as "foo" inside the function is the result
variable - hence "i => foo" doesn't make sense.


function foo()
  integer :: foo
  procedure(), pointer :: i
  i => foo  ! Invalid RHS - in this context "foo" the RESULT variable
            ! To use the procedure name, a RESULT(...) has to be specified
end
