Subject: Re: How to know what class are there in a script file?

The activesupport Dependency thing is really nice since it works with
any constant, but if you really want the classes only, this seems to
do the trick:

require 'enumerator'

klasses_before = Enumerable::Enumerator.new(ObjectSpace, :each_object,
Class).to_a

require 'open-uri'

new_klasses = Enumerable::Enumerator.new(ObjectSpace, :each_object,
Class).to_a - klasses_before

p new_klasses
