Comment(by simonpj):

 If we are going to change primpops, perhaps we should change `dataToTag#`
 and `tagToEnum#` to take/return `Word#` instead of `Int#`?  Wouldn't that
 be more consistent?  It's a breaking change (for primop users), but
 changing the type of the comparision primops is a much more substantial
 breakage.

 Please can we ensure that the wiki page is up to date, explaining the
 actual proposed story and why it's better.  Maybe it is already.

 Simon
