Factor programming language

Hi guys, so I took it up on Slava's words,
and tried.
http://paste.factorcode.org/paste?id=1713

I haven't tested much as I just wrote it.
But it seems like it works. (i think the calculation is ok too, but my 
math is lousy so..)

there are two versions, one is based on an array, the other on a hashtable.
anyway, you can see it as public domain, if you want to refine and put 
in the library, go ahead.

Hi there,

What's the best way to learn Factor inside-out - more theory not so much the
implementation?

By best I mean to have a good end-to-end understanding.

A good analogy would be to get a map of Factor's landscape - I don't want to
and probably won't ever visit all the places on the map but it would be nice
to know where I currently stand and where I can go exploring without getting
utterly lost asking to be saved every time (as I am now, more or less).

Thanks!
