optional<T>¶

This is an implemention of optional from the standard library. If it detects that a proper optional exists, it will attempt to use it. This is mostly an implementation detail, used in the sol::stack::check_get and sol::stack::get<optional<T>> and sol::optional<T> maybe_value = table["arf"]; implementations for additional safety reasons.

See this example here for a demonstration on how to use it and other features!
