I have, and can't believe that functionality this fundamental is not
API. But I have looked at several packages and am not seeing it. I
suspect that either it's so low-level that it's just not exposed as API,
or just that there is API but I'm not seeing it in the package docs
("hidden in plain sight"). Hence I ask
>> Am I missing something?
