Whenever I try to include a Timbre `p` statement in a function I get an error:

**project.clj**

```
 (defproject sketch "0.1.0-SNAPSHOT"
      :description "FIXME: write description"
      :url "http://example.com/FIXME"
      :license {:name "Eclipse Public License"
                :url "http://www.eclipse.org/legal/epl-v10.html"}
      :dependencies [[org.clojure/clojure "1.5.1"]
                     [com.taoensso/timbre "3.1.1"]])

```

**core.clj**

```
(ns user (:require [taoensso.timbre :as timbre])) 
(timbre/refer-timbre)

(defn tst [a]
  (p :tf (+ a a)))

```

**Output** (cider/nrepl)

```
 Unable to resolve symbol: p in this context, compiling:(NO_SOURCE_PATH:2:3)

```

But other Timbre functions/macros like `profile` and `spy` work fine.
