| /* 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 "" |

| 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. |
| Fortran: use A, localname => x |
| import_src = "A" |
| import_dest = local scope of the import statement even such as "" |

| alias = NULL |

| 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. |

| C++ cannot express it, it would be something like: using localname |
| = A::x; |

| alias = "localname" |

| excludes = NULL |
| The declaration will get imported as localname or |
