sol::light compile error

[qinix]

I got following error when using sol::light

/.../sol2/include/sol/stack_push.hpp:655:29: error: invalid ‘static_cast’ from type ‘<unresolved overloaded function type>’ to type ‘void*’
  655 |    lua_pushlightuserdata(L, static_cast<void*>(l.value));
      | 

After diving the source code, I found inconsistency on unqualified_pusher<light<T>>. The unqualified_pusher<light<T>> is using light<T>.value as a pointer, but in light<T>'s definition, light<T>.valule is a function returning a pointer.

sol2/include/sol/stack_push.hpp

Lines 649 to 658 in 6409634

	template <typename T>
	struct unqualified_pusher<light<T>> {
	static int push(lua_State* L, light<T> l) noexcept {
	#if SOL_IS_ON(SOL_SAFE_STACK_CHECK_I_)
	luaL_checkstack(L, 1, detail::not_enough_stack_space_generic);
	#endif // make sure stack doesn't overflow
	lua_pushlightuserdata(L, static_cast<void*>(l.value));
	return 1;
	}
	};

sol2/include/sol/types.hpp

Lines 236 to 238 in 6409634

	T* value() const {
	return m_value;
	}
