wait, why not? doesn't sound too painful. at least the lesser evil.

Lame sauce. Thanks for looking though. Yeah, I didn't see anything in MemCache API either. Lame sauce. Thanks for looking though.

This API doesn't offer a command get a list of keys off all cached data. Without that it's impossible to implement #delete_matched efficiently. So I gave up to publish a hack for your problem.

As far as I know, Memcache doesn't support such matchers.
