bool is_emptyset () const
Return true if this is empty.
bool is_indeterminate () const
Return true if this is indeterminate.

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.
