With a warning?

so 
  puts c
is 
  puts self.c  # instance variable, not method

Anyway, accessors are broken inside the class' instance methods (and sometimes we want
them, when they do non-trivial things).

Ummm, now I realize that your idea corresponds exactly to defining
automagically accessors for each i.v. .

I see, but this doesn't change the fact that I'd have to prefix locals,
which are far more common.

OK, but there's a name clash anyway :)
