Forth is an incredible language but it can't do all i want,
or i would use it for a loooong time. It also introduces a lot of things that
can interfere with the algorithms, or at least make you forget about
what you want to do. Finally, the largest scope that i could globally
optimize by hand is 100 or 120 instructions per block. we need to go beyond
that. Forth is the contrary of a dataflow graph analysis tool because
it over-serialises the computations.

at least, with a good VHDL background, you're used to write
a lot of testbenches. that's one good reason to reuse of
lot of its concepts.

I think about this program :
 - 1) make a dumb but flexible backend for, but not tied to, gcc
 - 2) enhance the backend
 - 3) create a VHLD-like frontend (without the hassles).
 - 4) create some basic libraries.
