Functions defined with defn- can be referenced from other namespaces

[smeghead]

Q	A
Phel version	0.15.1
PHP version	8.2.22

Summary

Functions defined with defn- can be referenced from other namespaces.

https://phel-lang.org/documentation/api/#defn-1

(defn- name & fdecl)
Define a private function that will not be exported.

I think the specification is that functions defined with defn- cannot be referenced from another namespace.

Current behavior

Functions defined by defn- in another namespace are available for reference.

How to reproduce

• src/other.phel

(ns defn-access\other)

(def public-value "this is public value.")

(def- private-value "this is private value. THIS MUST BE INVISIBLE.")

(defn public-function []
  "this is public function.")

(defn- private-function []
  "this is private function. THIS MUST BE INVISIBLE.")

• src/main.phel

(ns defn-access\main
  (:require defn-access\other))

(println other/public-value)
(println other/private-value)

(println (other/public-function))
(println (other/private-function))

$ vendor/bin/phel run src/main.phel 
this is public value.
this is private value. THIS MUST BE INVISIBLE.
this is public function.
this is private function. THIS MUST BE INVISIBLE.

You will see that variables and functions defined with def- and defn- in another namespace are available for reference.

Expected behavior

I would expect an error to occur when referencing a variable or function defined with def- or defn- in a different namespace.
