  # This implements call logic, which is simply like a c call (not send, that involves lookup and all sorts)
  #
  # The only target for a call is a CompiledMethod, so we just need to get the address for the code
  # and call it.
  #
  # The only slight snag is that we would need to assemble before getting the address, but to assemble
  # we'd have to have finished compiling. So we need a reference.
