Class registry conflict with Twitter Block module

After playing around with the Twitter module and figuring out it didn't support the search API (but it's in the todo and in planning since 2009 at least...), I turned my attention to http://drupal.org/project/twitter_block and ran into a conflict.

Both modules declare a TwitterSearch class. Twitter module's is empty, while the one used in Twitter Block holds the whole functionnality. I'm not sure how the class registry is supposed to work, but it looks like you can't have two classes with the same name. I've opened an issue with Twitter Block too: #1211770: Rename TwitterSearch class to TwitterBlockSearch (conflict with twitter.module).
