62 | says that names from namespace IMPORT_SRC should be visible within |
63 | namespace IMPORT_DEST. These form a linked list; NEXT is the next | |
64 | element of the list. If the imported namespace or declaration has | |
65 | been aliased within the IMPORT_DEST namespace, ALIAS is set to a | |
66 | string representing the alias. Otherwise, ALIAS is NULL. | |
67 | DECLARATION is the name of the imported declaration, if this import | |
68 | statement represents one. Otherwise DECLARATION is NULL and this | |
69 | import statement represents a namespace. | |
