It doesn't seem a very high cost to me.  Anything that makes the
language more accessible to users is well worth the effort.  Should
I propose a new issue on this or can we cover it with an old one?

BTW - I have always found oneOf to be a misleading name for this
construct, whereas enumeratedClass identifies its purpose nicely for me.
