There are also *tons* of public APIs which are now ints and would
benefit from becoming named values, but only if doing so doesn't break
compatibility (i.e. if they are still usable everywhere an int can be

Because the whole functionality is not important enough to have two
slightly different variations on it in the stdlib? And why is it a
poorer solution exactly?
Really, there can be two kinds of enum values (or named values):
- int-alike values (usable everywhere an int is)
- str-alike values (usable everywhere a str is)
A third kind of value, which is partly int-compatible but not entirely,
sounds like a byzantine subtlety to me.
