The current implementation presented here resolves an issue I ran into:
```
subroutine acccase( var )
  integer ::  var
  integer :: res(10)
  select case ( var )
    case ( 1 )
      print *, "case 1"
      !$acc serial
      res(1) = 1
      !$acc end serial
    case ( 2 )
      print *, "case 2"
    case default
      print *, "case default"
  end select
end subroutine
```

The first iteration here, even if not perfect, is usable for some cases. I support the conversation on a more complete solution though - and seems to me that it can be done even if this first implementation is merged :) Thank you for looking into this!
