Oh, I see. Well, I'm just trying to trans-implement numbers to be classes,
not single instances.(as in Fixnum, or just-in-time-instances as in Bignum).
Just to be consistent with human cognition/natural language.

Anyone imagine easy way to implement this?
Just for it to work, performance is not an issue at the moment. Hmmm I
suppose I would have to manipulate the Ruby parser...

Hints are very welcome!

Ask me for details if description not clear!

#example of usage:
That would for example mean that you coluld implement
the must-be-in tutorial algorithm example of the factorial like this:
(in pseudo-Ruby)

def PositiveInteger.fact(x); x*(x-1).fact; end
def 1.fact;1;end

(of  course it would have to be dynamically implemented, since the number of
numbers is unlimited, something similar to
