[MLton-user] Re: Wish for a standard sum type

[Henry Cejtin]

You are right that it isn't consistant with SOME and NONE, but that is because
those aren't consistant with many of the other datatypes in the standard
basis library.  Look at Array2.traversal, Date.weekday, Date.month and some
of the others.

I think that the first-letter-capitalized convension is WAY better and see
enough examples in the standard basis library that I would go that way.
