A scenario where analyzer fails on dependent defs

[zampino]

This reproduces the same problem of Clerk evaluating notebooks with inter-dependent LaTTe definitions.

(ns scratch
  (:require [scratch.macros :refer [dep-def]]))

(dep-def X)
(dep-def Y X)

(ns scratch.macros)

(defmacro dep-def [name & deps]
  (assert (every? #(some-> % resolve bound?) deps)
          "All deps must to be defined and bound at macro-expansion!")
  `(def ~name {:name '~name :refs '~deps}))

The assertion kicks in when analyzer encounters the second form in the scratch namespace above, and the forms have not been evaluated before.
