My intended use of the term 'subclass' is as the Haskell report: https://www.haskell.org/onlinereport/basic.html "class Num of numeric types is a subclass of Eq, since all numbers may be compared for equality" Of course what I have written may not be consistent with the report.

HelloPat,

I am not sure if terms *superclass* and *subclass* are applicable to Haskell classes.

Haskell class is very different from Java class. It is more like an interface.
