 Please add warning to docs (like basic usage of tribool) that you can't
 write like this.


 [[BR]]
 [[BR]]

 false==0, so it casted to function pointer, so this expression is always
 '''indeterminate''', not false:
 {{{
 tribool a = 0? indeterminate : false;
 }}}

 [[BR]]
 [[BR]]

 true!=0, so cast goes other way - indeterminate casted to bool, this
 epression always '''true''', not indeterminate:
 {{{
 tribool b = 1? indeterminate : true;
 }}}
