Hello all, small question: there seems no xor operator in c++ but there is also no Boost xor functor (like the std::logical_and)? Scenario: I have 2 data members used in variant like way: only 1 may be valid. Both valid or both invalid is incorrect.
Can't you use !!A != !!B? (or !!A ^ !!B)
ah quite brilliant! I was thinking about the (a ? !b : b). Still a logical_xor does also has a documentation value.
