OOP turn on

<syntaxhighlight lang="lua">

==Example 1==
Import specified functions
<syntaxhighlight lang="lua">
import("function1,function2"):from("myScript") -- import functions "function1" and "function2" from script "myScript"
-- now "function1()" is same as "exports.myScript:function()"
function1("test")
</syntaxhighlight>

==Example 2==
Import functions which contain string
<syntaxhighlight lang="lua">
import("function,otherFunctions"):from("myScript") -- import functions contain "function" in name, in this example import "function1" and "function2" from script "myScript"
function1("test")
</syntaxhighlight>

==Example 3==
Import all functions
<syntaxhighlight lang="lua">
import("*"):from("myScript") -- import all functions, in this example import "function1" and "function2" from script "myScript"
function1("test")
</syntaxhighlight>
