I've very tempted to combine your work with this and then go on to define rationals and then the reals. The reals would be very interesting since it would be a sequence that takes an epsilon and gets a rational number that is close enough. It's kind of crazy to think that all these real numbers are infinite cauchy sequences.
If I define a real as function(eps) { return some_rational; } then I could define it piece_wise and say function mult_real(a,b) { return function(eps) { return a(eps/2) * b(eps/2); } }
I just did a construction of the integers assuming either sets or arrays. I could equally have used your list definition.
