How about replacing the 'if(0)' type check with type traits

[yuansip]

Wonderful example, just one comment, you hope to check if FUNC is the function type needed at compile time, how about use type traits? like:

include <type_traits>

// replace if(0) { xxxx } with following statement:
static_assert(std::is_same(FUNC, std::function<void(const State&)>)::value, "FUNC must be type of std::function<void(const State&)>");

no, func is not of type std::function, but callable with const State&
parameter.

of std::function");
