Why would that one be curried?  It's completely boring, returns a list,
and its internal function x2 is totally straightforward (not even a
closure) and is invisible to the caller.

Slightly more interesting is

(define (fie a)
  (lambda (x) (+ x a)))

which is equivalent to the curried definition

(define ((fie a) x) (+ x a))

However, the currying is not a feature of the semantics (the semantics
of returning a function or more often a closure, namely a function with
an environment in the form of variables imported into its scope) but of
the syntax.

So while the second definition of fie is a curried definition, the first
equivalent definition isn't.
