Good use-cases for boolean overloads in addition to DSLs:

https://en.wikipedia.org/wiki/Fuzzy_logic
https://en.wikipedia.org/wiki/Three-valued_logic
https://en.wikipedia.org/wiki/Four-valued_logic

etc...

Although I think it might be more readable to have "and", "or" 
etc as operators. This is actually allowed in C++:

"a && b" <=> "a and b"…
