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.

89 C++ has no way to import all names except those listed ones.

103 "localname". "x" is not defined as a local name by this statement.
