49 /* This struct is designed to store data from using directives. It
50 says that names from namespace IMPORT_SRC should be visible within
51 namespace IMPORT_DEST. These form a linked list; NEXT is the next
52 element of the list. If the imported namespace or declaration has
53 been aliased within the IMPORT_DEST namespace, ALIAS is set to a
54 string representing the alias. Otherwise, ALIAS is NULL.
55 DECLARATION is the name of the imported declaration, if this import
56 statement represents one. Otherwise DECLARATION is NULL and this
57 import statement represents a namespace.
59 C++: using namespace A;
62 import_dest = local scope of the import statement even such as ""
68 Fortran: use A, only: x
70 import_dest = local scope of the import statement even such as ""
74 The declaration will get imported as import_dest::x.
76 C++ has no way to import all names except those listed ones.
77 Fortran: use A, localname => x
79 import_dest = local scope of the import statement even such as ""
85 import_dest = local scope of the import statement even such as ""
89 All the entries of A get imported except of "x". "x" gets imported as
90 "localname". "x" is not defined as a local name by this statement.
92 C++: namespace LOCALNS = A;
93 Fortran has no way to address non-local namespace/module.
95 import_dest = local scope of the import statement even such as ""
99 The namespace will get imported as the import_dest::LOCALNS
102 C++ cannot express it, it would be something like: using localname
104 Fortran: use A, only localname => x
106 import_dest = local scope of the import statement even such as ""
110 The declaration will get imported as localname or
111 `import_dest`localname. */
