IMPORTING ALL PARAMETERS INTO A NAMESPACE:

          $query->import_names('R');

       This creates a series of variables in the 'R' namespace.
       For example, $R::foo, @R:foo.  For keyword lists, a vari-
       able @R::keywords will appear.  If no namespace is given,
       this method will assume 'Q'.  WARNING:  don't import any-
       thing into 'main'; this is a major security risk!!!!
