Does "Screw backward compatibility in favor of OOP" extend to "Screw
backward compatibility in favor of generic programming"?  I'd like to
template FunctionBase around its return value type, but even with the
default template argument "typename Output=Number", code which uses
FunctionBase has to be rewritten to use FunctionBase<>.
