Detailed Description
       bool_set

       See N2136, Bool_set: multi-valued logic by Herve Bronnimann, Guillaume
       Melquiond, Sylvain Pion.

       The implicit conversion to bool is slippery! I may use the new explicit
       conversion. This has been specialized in the language so that in
       contexts requiring a bool the conversion happens implicitly. Thus most
       objections should be eliminated.
