IMO an object pointer should be declared sqOop to clearly distinguish
it from some something that is intended to be used as an integer. And
a (32- or 64-bit) location in the object memory should have its own type
declaration that would just coincidentally be the same size as a sqOop
in the current implementations. And maybe there should be one more type
definition to represent the 32-bit words in an indexable object.
