13	ChoiceOf constraint is broken	Brian Warner		"robk ran into this one. I think the patch is to add a method override to {{{PolyConstraint}}}:

{{{

    def checkToken(self, typebyte, size):
        ok = False
        for c in self.alternatives:
            try:
                c.checkToken(typebyte, size)
                ok = True
            except (Violation, BananaError):
                pass
        if not ok:
            raise Violation(""does not satisfy any of %s"" \
                            % (self.alternatives,))
}}}

Although it seems like the {{{raise BananaError}}} in Constraint.checkToken
(used as the default for a lot of Constraint subclasses) is inappropriate,
and maybe it should be raising a Violation instead. I'll have to think about
the implications of that.
