Subject: [ruby-talk:12892] find.rb

Hello, I'm new Ruby and I like it very much. The dynamic extensibility
and iterators are very useful. 

I was working with lib/find.rb and found that it would choke on
Permission denied errors so I added EACCES to the rescue expression.
It's a 15 byte difference, but here's the patch anyway:

            end
          end
-       rescue Errno::ENOENT
+       rescue Errno::ENOENT, Errno::EACCES
        end
       end
     end


I also found it useful to extend the Find module with a collect-like
method (with an optional block) so I could generate an array of files.
I was surprised how cleanly this could be done--I didn't have to make
my own version of the module or make some random function that I'd end
up recoding every time I needed.
