My personal stance and I what I use on projects is something a little different and I try to evangelize: Make an overloads template that just works with apply_visitor or an apply_visitor like function:
apply_visitor( overloads( [](A & a){ cout << "it's a A!"; } [](B & b){ cout << "oh, a B!"; } [](C & c){ cout << "ah yes, a C!"; } [](auto & d){ cout << "a default!"; } ),
v
);
I use syntax like this: case_<void>(v)( [](A & a){ cout << "it's a A!"; } [](B & b){ cout << "oh, a B!"; } [](C & c){ cout << "ah yes, a C!"; } [](auto & d){ cout << "a default!"; } ); Which I think is a little neater. You can implement this in C++14 with Fit like this: template<class T, class Result> Result case_(T& x) { return [&](auto&&... fs) { return apply_visitor(x, fit::result<Result>(fit::match(std::forward<decltype(fs)>(fs)...)) ); }; } This could also be extended to support multiple variables as well.
