Detailed Description

       bool_set

       See N2136, Bool_set: multi-valued logic by Hervé Brönnimann, 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.
