  47 /* This struct is designed to store data from using directives.  It
  48    says that names from namespace IMPORT_SRC should be visible within
  49    namespace IMPORT_DEST.  These form a linked list; NEXT is the next
  50    element of the list.  If the imported namespace or declaration has
  51    been aliased within the IMPORT_DEST namespace, ALIAS is set to a
  52    string representing the alias.  Otherwise, ALIAS is NULL.
  53    DECLARATION is the name of the imported declaration, if this import
  54    statement represents one.  Otherwise DECLARATION is NULL and this
  55    import statement represents a namespace.
