Racket also has type-specific fl/ and unsafe-fl/, which we
use extensively in our type-specific part of code.

I see your point, and I have nothing against Forth per se,
and rewriting the whole thing in Forth could be an
interesting research, but well, sometimes we need
to deliver programs in time.

BTW, links to http://www.forth.org/novice.html
and http://www.taygeta.com/ do not work. I will
keep them in mind, though--I would like to look
at them.

I am from Russia -- you could guess from my email :)
