Subject: Newbie regex question about \w

I'm trying to parse ruby files to find all the class definitions in the 
file. For each line in the file, I thought I could use the following to 
pull out the class name:

\bclass\b(\w+)\b

so then $1 would give me the class name.

But it doesn't work:

irb(main):001:0> line = "class Article < MyBaseClass"
=> "class Article < ActiveRecord::Base"
irb(main):002:0> line =~ /\bclass\b(\w+)\b/
=> nil

I think I narrowed down the problem to my use of \w, but I can't 
understand why.

For extra credit, anybody know how I can make sure I can ignore comments 
and quoted strings?  I want to make sure I ignore these things:

if option_exists # handle class options

as well as

puts "Your are in a class by yourself"

But those are advanced... if I can just get the first one working I'll 
be grateful!

Thanks,
Jeff
