Wither Self

[Joe Armstrong]

    Shouldn't there be a Self in funs?

    IMHO writing:

	Fac = fun(0) -> 1;	
		 (N) -> N*Self(N-1) end
 
    is just teensy weensy bit simpler than:

	Fact = fun(X) -> 
            G = fun(0, F)  -> 1; 
                   (N, F) -> N*F(N-1,F) 
                end, 
            G(X, G) 
          end.
  
    I don't really know my way around the code base since it's been
reorganised - it should be just a quick hack in the linter and 
lambda lifter - but what these are called today I have no idea :-)
