That is, what the options are, and why this is the best option (which is not the option that the previous RFC on this topic picked). It would also be nice to cross-reference semantics of ?-> in other languages that have it, to make sure we don't introduce any unexpected WTFs for people switching between languages. I *think* the specified behavior is consistent with what everyone else does, but I haven't checked to be sure. Regards, Nikita
