Well, that's already stated to be one of the requirements for being
immutable or stable, so I think we need a term that's a bit stronger.
The real issue here is that the notion of what is a side effect is
much much broader than what we have used in the past. I don't think
we clarify that by continuing to use the same term "side effect".
