Pivy problem and some other stuff

[azrael]

Look, what I think about is this.
I'd like to make a multi dimensional list in which evry single element
would represent a function. By looping through the list I would
execute the functions. But not only that, it is possible to experiment
with recoursions.
the return 1 2 and 3 examples are just a examples. Of course that the
thing I'm thinking about is a little bit more complex.
