Re: Combining mutable objects with const references

Oh, no I think I understand you now, rossb. You're saying that
mutability is dangerous *unless* we make it safe with the appropriate
compiler rules. But that's the whole point of the thread! ...I don't
think I've misunderstood you. You say it wouldn't be trivial to
implement this. That doesn't necessarily mean it isn't a good feature
to have.
