+&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Prefer tickets; often when people have issues it highlights an

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Of course, in the context of the Erlang VM, these two snippets

-are equivalent; there is nothing preventing you from calling the

-&lt;code&gt;in_module&lt;/code&gt; module from any other module. The &lt;code&gt;mod&lt;/code&gt;

-instruction means a module should be created in the Erlang VM,

-with no concept of scope attached.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Still we need to handle both. To do this we will add a step

-between the parser and the code generator that will walk over the

-abstract syntax tree, from here onward shortened as &lt;em&gt;AST&lt;/em&gt;,

-and transform the AST by executing it where applicable.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What happens when you execute a &lt;code&gt;mod&lt;/code&gt; instruction?

-A module is created. Since we are compiling, that simply means

-the compiler will branch out and create a module.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;If everything is an expression, does that mean this will allow

-me to create modules at runtime using the same syntax? Yes, but

-let&amp;#8217;s not get ahead of ourselves yet.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;For now we will just iterate over the AST, and will compile

-a module for each &lt;code&gt;mod&lt;/code&gt; found. Modules cannot contain

-expressions yet, so there&amp;#8217;s no need to recurse over it at this

-point. This should solve the compilation of our first snippet.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;The &lt;code&gt;compile/1&lt;/code&gt; function becomes:&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;Everything looks fine. And we can check that the two modules have

-been loaded into the VM:&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;paragraph&#34;&gt;&lt;p&gt;What about the second snippet? It brings up many questions. What

-happens once a &lt;code&gt;mod&lt;/code&gt; expression has been executed at

-compile time? If it&amp;#8217;s an expression then it has to have a result,

-right? Right. We are still a bit lacking with expressions for now,

-though, so let&amp;#8217;s get back to it after we add more.&lt;/p&gt;&lt;/div&gt;

-&lt;div class=&#34;ulist&#34;&gt;&lt;ul&gt;

-&lt;li&gt;

-&lt;p&gt;

-&lt;a href=&#34;https://github.com/extend/xerl/blob/0.2/&#34;&gt;View the source&lt;/a&gt;

-&lt;/p&gt;
