:use in namespace does nothing

[mabasic]

This code runs correctly:

(ns hello-world\boot)

(def app (php/new \Laravel\Lumen\Application "/home/mabasic/code/src/test/hello-world/"))

(php/-> app (run))

This code also runs correctly:

(ns hello-world\boot
    (:use \Laravel\Lumen\Application))

(def app (php/new \Laravel\Lumen\Application "/home/mabasic/code/src/test/hello-world/"))

(php/-> app (run))

What is the purpose of (:use \Laravel\Lumen\Application) if the file runs either way?

I was expected to get an exception or error if the php class was not included with :use in the file.

Update: Does (:use \Laravel\Lumen\Application) mean that I can reference that class by just using Application. If so, how can I alias it to something else? Also, how do I use a imported phel library? Did I miss that in the documentation?

Correct. You can just use Application now. You can also define an alias:

(ns hello-world\boot
  (:use \Laravel\Lumen\Application :as MyAlias))

Also, how do I use a imported phel library? Did I miss that in the documentation?

Instead of :use you need to use :require.

(ns hello-world\boot
  (:require hello-world\test))

# Call a function in test
(test/my-fn)

Alias is also supported

(ns hello-world\boot
  (:require hello-world\test :as something))

# Call a function in test
(something/my-fn)

The documentation definitely needs some update on this topic!

Thank you for explaining. On it :)
