John McCall afdda3d107 Implement SE-0117.
One minor revision: this lifts the proposed restriction against
overriding a non-open method with an open one.  On reflection,
that was inconsistent with the existing rule permitting non-public
methods to be overridden with public ones.  The restriction on
subclassing a non-open class with an open class remains, and is
in fact consistent with the existing access rule.
