Hi John,

This looks good to me, with a couple minor nits below.

I wonder about tweaking this comment to avoid talking
about breakpoints, since this enum is not really strictly
about breakpoints anymore.

You have a "\n" in the middle of some lines above.  Was that intended?
I'd expect to see instead lines broken at \n, ending with \n\ .

This isn't necessary, AFAICS.

Space before parens, line break after return type.
We follow GNU convention in tests too, unless different syntax is
relevant for the test.
