Notice that solving the initial problem with ActivateService would only
require that ActivateService could take a single string argument and
have a default for the (until now unimplemented&undocumented anyway)

For the general problem, introspection probably isn't a complete
solution: can't I write a method that will take different arguments
depending on the first that is being sent? If so, then how should that
method be introspected?
