I noticed that if you ‘include’ a module within a method, it will polute  
the  
namesapce that defines that method. I found a simple solution is to  
declare a  
throw-away class, and execute my code in that. Is there a more better  
way to  
achieve this?

# Pollutes current namespace

def init()  
include Inertia

do\_stuff\_with\_inertia()  
end

# Doesn’t polute namespace, but ugly

class DontPolute  
include Inertia

do\_stuff\_with\_inertia()  
end

both pollute your namespace equally. the first pollutes class Object,  
the  
second class DontPolute. remember that you’re code in ruby, if not  
inside a  
class, is inside the Object class. this allows you to pretend your  
coding  
something like perl. i always write main programs like so

class Main  
…  
end

Main::new if $0 == **FILE**

to avoid any such issues.

if you are looking for a workaround you can also use

Module::new{ include Inertia … }

Instead of include, you may want:  
require ‘intertia’

This will load up inertia.rb, which i’m assuming contains either a class  
or a  
module name Intertia. Then you can use it via Interia.new() or  
Intertia::do\_stuff\_with\_intertia().

Correct me if I’m misunderstanding what you’re trying to do here.
