Subject: ideas for a JIT optimizer

Currently I am thinking that an optimizer that takes

class A
  def one_thing
    calls_another 3
  end
  def calls_another a
    a.to_s
  end
end

and converts it to C, such that one_thing calls another *in c* would be
a good  JIT.

ex:
VALUE
one_thing_in_c(VALUE self) {
  return calls_another(NUM2FIX(3));
}

VALUE to_s = rb_intern("to_s");
VALUE calls_another(VALUE self, VALUE in) {
  return rb_funcall(in, to_s);
}

Any thoughts on this? Ideas? Suggestions?
This seems to be the next step for ruby2cext (which almost does this,
but not quite).
Thanks much.
