having built my own Lisp by learning Clojure I think Clojure does broke some ability of homoiconicity in small features.

Say I have `{:a 1}`, which is equivalent to `(hash-map :a 1)`, I take it as data and I can recreate the expression with the later form:

    user=> (quote (hash-map :a 1))
    (hash-map :a 1)
    user=> (def a (quote (hash-map :a 1)))
    #'user/a
    user=> (list (nth a 0) (nth a 1) (nth a 2))
    (hash-map :a 1)

but for `{:a 1}`, I got error since it's a bit different:

    user=> (def b (quote {:a 1}))
    #'user/b
    user=> (list (nth b 0) (nth b 1) (nth b 2))
    Execution error (UnsupportedOperationException) at user/eval12 (REPL:1).
    nth not supported on this type: PersistentArrayMap
    user=> b
    {:a 1}

now it's different, it's no longer homoiconic in this syntax.

    user=> (first b)
    [:a 1]

I would rather not using this syntax in my own lisp and still using a prefixed version.
