Instrumenting a function fails when more than eight keys are destructured

[dpassen]

Expected behavior

Functions are capable of being instrumented for debugging, regardless of how many keys are destructured.

Actual behavior

An error is thrown when instrumenting a function when more than eight key-value pairs are associatively destructured.

class clojure.lang.Symbol cannot be cast to class clojure.lang.Keyword (clojure.lang.Symbol and clojure.lang.Keyword are in unnamed module of loader 'app')

Steps to reproduce the problem

Use cider-debug-defun-at-point on the following function definition:

(defn can-not-instrument
  [{one   :one
    two   :two
    three :three
    four  :four
    five  :five
    six   :six
    seven :seven
    eight :eight
    nine  :nine}]
  (format "%s-%s-%s-%s-%s-%s-%s-%s-%s" one two three four five six seven eight nine))

That's a pretty weird issue! @alexander-yakushev would be able to take a look?
