-/* This struct is designed to store data from using directives. It
- says that names from namespace IMPORT_SRC should be visible within
- namespace IMPORT_DEST. These form a linked list; NEXT is the next
- element of the list. If the imported namespace or declaration has
- been aliased within the IMPORT_DEST namespace, ALIAS is set to a
- string representing the alias. Otherwise, ALIAS is NULL.
- DECLARATION is the name of the imported declaration, if this import
- statement represents one. Otherwise DECLARATION is NULL and this
- import statement represents a namespace.
-
- C++: using namespace A;
- Fortran: use A
- import_src = "A"
- import_dest = local scope of the import statement even such as ""
- alias = NULL
- declaration = NULL
- excludes = NULL
-
- C++: using A::x;
- Fortran: use A, only: x
- import_src = "A"
- import_dest = local scope of the import statement even such as ""
- alias = NULL
- declaration = "x"
- excludes = NULL
- The declaration will get imported as import_dest::x.
-
- C++ has no way to import all names except those listed ones.

- excludes = ["x"]
- All the entries of A get imported except of "x". "x" gets imported as
- "localname". "x" is not defined as a local name by this statement.

- import_src = "A"

- alias = "localname"
