This would be all integers, to support the request from Matthew.

I also believe, after a quick check with Joe, that it=E2=80=99s not possibl=
e to add
a flag to an integer (=E2=80=9Cnon reference counted types are stack alloca=
ted, ie
the zval on either side of a call boundary are unique=E2=80=9D). So it coul=
dn=E2=80=99t
work the same way.
