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.
