+More type functions
+~~~~~~~~~~~~~~~~~~~
+* Allow {tv = TYPE ty) as a non-rec binding in Core
+* Use this to make equality constraints more uniform
+* Can a Dict can contain an EqPred?
+ How does that differ from an EqInst?
+* Make DictBinds into Core
+
+* In zonking, do we need to zonk the kinds of coercion variables?

* A Given inst should be a CoVar, not a coercion
