Forgot to say: nicely written!
Some more comments:
You can declare a fixity (infixr) for flop instead of using parentheses
(yes, this is allowed; see 'elem' in the Prelude). Would make the code more
"(Recall that a type definition is just like a data definition, but with no
choice operator (|).)" First, you mean to say 'newtype', not 'type' (as in
the code). Second, a newtype may also contain only one data element (i.e.
one type expression after the constructor), not many, as in a data type
definition. Third, newtype is unlifted.
