I have some working non rails standalone ruby code under ruby 1.8.6  
using activesupport 2.3.5 to take a string and make it into a class  
name. I was doing this:

require “active\_support”  
classes = []  
classes \<\< “health\_report”.classify.constantize

Now under ruby 1.9.2 and rails beta4 it fails. classify is not valid  
and I am not sure of constantize. Is there a new way to take a name  
of a file and make it into a class name so it can be used. I have a  
list of ruby files that contain an individual class. I can require the  
file but I do not know the name of the class. I was using the file  
basename classified and constantized to create the class name that I  
later can use.

Active Support now extends practically nothing by default (so it is  
less heavyweight by default).

This is a guide about AS core extensions I am writing myself (work in  
progress, due for Rails 3):

```
http://edgeguides.rubyonrails.org/active_support_core_extensions.html#how-to-load-core-extensions

```

That particular section explains how to import stuff, there are several  
options.
