**Use 2**: A lightweight alternative to boost::variant when only 2 components are required (either relates to variant in a similar way that pair relates to tuple ). (...)

either eitherAOrB;

if( eitherAOrB.is_left() ) std::cout << "A: " << eitherAOrB.left(); else std::cout << "B: " << eitherAOrB.right();

Is there any particular reason not to follow std::pair naming and use first() and second() members?

first()/second() implies a sequence with at least two elements.

Good point, thanks. -- Mateusz Loskot, http://mateusz.loskot.net
