Implement F2023 19.4.2 conformance check for statement function dummy argument names Fixes: #203820 F2023 19.4.2 permits a statement function dummy argument to share its name with an **accessible** identifier only when that identifier is a scalar variable. Flang previously accepted all such clashes silently. ```fortran subroutine s real :: arr(10) real :: ok f(arr) = arr + 1 ! error: arr is an array h(ok) = ok + 1 ! ok: scalar variable shadowing is permitted end subroutine ``` Assisted-by: Claude
