so many relied (implicitly( on some builtin function
after all can't do much in ruby without calling
Now all those dependencies are explicit
Small risc changes come because the macro version has a return label and unreachable label
as it was before blocks
(thought blocks would make reuse of messages impossible, but was wrong, this only appilies to lambdas)
(too) many tests affected
especially positioning makes the previous interpreter approach to
fragile (too far off the real thing)
Interpreter should be it’s own platform (still use the risc
instructions),
get a translator and use positions
