I'm begining to understand it. "Criticizing" it's just a tehnique to allow  
me to understand it better.

This is what I understood:

- there is no distinction of data from functions. This seem more like a  
matter of definiton: what I call X, the X + Y or just X.

- functions can be manipulated the same way as data. This does not sound  

- functions can be manipulated as easy as data. This seems better.

- functional programming is declarative. One may take a picture of all  
those pebbles, but their arrangemant does not make sense to him because no  
part of it resemble the original description.

- one cannot print "things" that cannot be traversed in a sequential way

The last two seems to be in contradiction.
