those fields are already present in the classes
(in the future they should be defined in some and integrated to ruby,
but that would mean parsing to boot and parsing doesn’t yet work on
opal)
simplification, new model is such that the upon start the method:
has a message in r0, works on it and returns to the return address.
Everything else is up to the caller
the source was there long before the compiler (sis language) came along
and was basically doing the same
Much clearer concept with using compiler to generate methods and code
Also move compile method to method
