Consider the following file:

module mymod
   use, intrinsic :: iso_c_binding

   public mytype

   type mytype
   contains
      final destruct
   end type

   enum, bind(C)
      enumerator one
   end enum

   interface myinterface
      module procedure foo
   end interface

contains

   subroutine foo(arg)
      integer arg
      allocatable arg(:)
   end subroutine

   subroutine destruct(self)
      type(mytype) self
   end subroutine
end module

Is it possible to modify it like below?

Here double colons are not necessary, though.
