Egg secretly has the feature.
See "egg/inlined.hpp".

You expect something like this?:
static_result_of<T_curry2(F)>::type c = BOOST_EGG_CURRY2({}); // static
boost::result_of<T_curry2(F const &)>::type c = curry2(f); // dynamic
stateless_result_of<T_curry2(F)>::type c = BOOST_EGG_STATELESS(); // for stateless one.
