Thanks for your review, and it's great to know of a use case that this
helps.

Sounds good; will do.

Will do.

OK - I'll change it to 2 spaces.

There was a recent discussion on the list [1] about whether bitsets
should be enums, and we decided against it. But anyway we can revisit
this later if need be.

The changes Taylor suggested were minor, so I'll hold off sending
another version until there are more substantial changes requested.
