Subject: Discovering the number of return arguments requested.

Is it possible ( and I think not ) that you can discover if any return 
arguments are requested when a method is called.

Eg:

def foo
   if nargout == 1
      "bar"
   end
end

a = foo # nargout == 1
foo     # nargout == 0


This would be useful in certain patterns where you only want to
create a return value and consequently a new object if it is
actually required.
