As with the original proposal, your examples here don't obey the Naming
Guidelines.
If we're going to pretend that Swift is C, we wouldn't have a distinction
between argument labels and parameter names in the first place!
Is there an example of two functions, obeying the naming guidelines, which have
different argument labels (not parameter names) for parameters of the same
type, where it makes sense to cross-call them?
