Ciao Stefano,

how are you?

not that i know.

try looking at:

http://library.wolfram.com/infocenter/MathSource/555/

and read the *.m file. that _might_ help you. this an old package, but 
still you may get an idea of what is happening. i think the reason why 
this is undocumented is that WRI would like to maintain the ability to 
change the internal code as they deem necessary.

i am sure you know:

http://www.verbeia.com/mathematica/tips/Tricks.html

or this is another small source of information:

http://documents.wolfram.com/v4/MainBook/2.5.15.html

i do not know how close mathematica is to the wizard book, but it is 
worth a try:

http://mitpress.mit.edu/sicp/full-text/book/book-Z-H-35.html#%_sec_5.5

hope that helps,
regards from freiburg,

oliver
