What error?  The only error I see there is the one you've just introduced,
where it is no longer true that 'any object responding to #do: can be
used as argument.'  What exactly is the problem you are trying to fix?

	Or why not have a doSmart: ?

I cannot understand this comment.  All I can figure out for sure from the
wording is that it is a complicated interface which I'm better off without.
