  40    says that names from namespace IMPORT_SRC should be visible within
  41    namespace IMPORT_DEST.  These form a linked list; NEXT is the next element
  42    of the list.  If the imported namespace has been aliased, ALIAS is set to a
  43    string representing the alias.  Otherwise, ALIAS is NULL.
  44    Eg:
  45        namespace C = A::B;
  46    ALIAS = "C"
  47    DECLARATION is the name of the imported declaration, if this import
  48    statement represents one.
  49    Eg:
  50        using A::x;
  51    Where x is variable in namespace A.  DECLARATION is set to x.
