Similarly you must know the layout of the objects you load into
register(s). You might need to expand sign for example. Consider an
advanced optimizer that loads small records and arrays into register sets.
What about fat pointer objects, loaded into registers while doing checks,
maybe loading memory pages etc.
However complicated implementation of a language construct in the machine
code is, that does not automatically make the construct high level, IMO.
