I know you use this scheme to be able to make this distinction. The point is that passing an option type as template's argument to set<typename T> gives the same information like passing an option type as a type of the argument of function.
The question is what does wrapping arguments of setOpt in the Options::X type give us? Later on it's convenient to have all options' types be derived from one base class (OptionBase) to treat them polymorphically in containers and alghorithms . But in the moment of setting an option using setOpt we don't really need this and we shouldn't force users to wrap all these values only to give them to setOpt method.
What do you think?
