i didn't know this kind of syntax.

btw, "not" a register does not need 2 instructions, one is enough.
you can don "xnor r0, src, dest" for example.

for loadcons, we can probably use another syntax or even a pre-processor :
i'm thinking about the in-source debugging.

btw, IIRC there is no debugger yet. there are plans for cross-emulators but
it is not enough, what will we do when the real chip will be available ?
we can use the emulator to debug the debugger stub, for example.
