There doesn't seem to be any built-in named functions that we expect to 
be used, so I suppose any such are either in custom files or third-party 
code (and are custom-written anyway). Then breaking those (asking the 
users to update them, basically) might not be the worst decision.

OTOH, the condition-case/wrong-number-of-arguments solution also should 
work 99,9% of the time, and that might cover all such functions in 
existence too.
