63 says that names from namespace IMPORT_SRC should be visible within
64 namespace IMPORT_DEST. These form a linked list; NEXT is the next
65 element of the list. If the imported namespace or declaration has
66 been aliased within the IMPORT_DEST namespace, ALIAS is set to a
67 string representing the alias. Otherwise, ALIAS is NULL.
68 DECLARATION is the name of the imported declaration, if this import
69 statement represents one. Otherwise DECLARATION is NULL and this
70 import statement represents a namespace.
72 C++: using namespace A;
75 import_dest = local scope of the import statement even such as ""
81 Fortran: use A, only: x
83 import_dest = local scope of the import statement even such as ""
87 The declaration will get imported as import_dest::x.
89 C++ has no way to import all names except those listed ones.
90 Fortran: use A, localname => x
92 import_dest = local scope of the import statement even such as ""
98 import_dest = local scope of the import statement even such as ""
102 All the entries of A get imported except of "x". "x" gets imported as
103 "localname". "x" is not defined as a local name by this statement.

106 Fortran has no way to address non-local namespace/module.
108 import_dest = local scope of the import statement even such as ""
112 The namespace will get imported as the import_dest::LOCALNS
115 C++ cannot express it, it would be something like: using localname
