I could add there is many assembler soon written. So maybe, it will be
more interresting to make a quick emulator. Whygee one is for proof of
concept. So, we need a quick one to run long program at raisonnable
speed.

If you put macro inside your asm, never forget to introduice the dot
(like .not), most of the time we expect that 1 instruction take 32 bits
but it could be much more with macro.
