You can even do better with something like: namespace StlHelpers { template<class... Ts> struct overload : Ts... { using Ts::operator()...; }; template<class

You can even do better with something like:
namespace StlHelpers {
template<class... Ts> struct overload : Ts... { using Ts::operator()...; };
template<class... Ts> overload(Ts...) -> overload<Ts...>;
template<class var_t, class... Func> auto visit(var_t & variant, Func &&... funcs)
{
return std::visit(overload{ funcs... }, variant);
}
}
And then
StlHelpers::visit(var,
[](MyType1 t1) {...},
[](MyType2 t2) {...},
[](auto t) {...}
);
