Datatypes that implement a single method can be more simply
represented as ordinary functions, e.g.

(defn fake-provider ...)

If you want to be really precise, most real numbers are an infinite
number of decimals.
If you encode them as a lazy seq of decimals, + - and other ops are doable.
Comparison is semi-decidable only: it terminates only in certain case
(finite number of decimals)
or when the number are different.

Then you can't use floats.

Back to my question: Am I trying to do Java in Clojure? Is there a more
Lisp-y way to do this?
You can hide the types so your client code is more lispy:

(def mp (make-mock-provider)) ... (load-page mp)
;;production
(def prov (make-provider)) ...
So for returns a lazy-seq of the combinations and I am forcing it to
process the values by filtering.
mmm...
I still tried your approach and nothing changed in processing time.
I changed the for form to filter as it is pairing the combinations, I
didn't think it would make any difference since I

The 'palindrome?' function can be made much faster. Your version --

checks for full equality with the original. There are faster (if
uglier) ways to check
