When you want to catch a Throwable or Error it is far better to catch only the specific type. I agree with you that non-local returns should be avoided but I wouldn't want to completely eliminate them from my code. BTW I really like Circumflex, keep up the good work!

I think that `return` from within closures should be avoided, not really catching `Throwable`s. Wrote about the same.

I really like Squeryl and I was really disappointed when I saw the vars inside SessionFactory. I should have kept reading the docs :-( I believe that we both agree that the mechanism with the static factories has some serious drawbacks but it can be used in smaller apps as a convenience. Thanks for letting me know! I'll update the article and I'll probably give Squeryl a try really soon :-) I didn’t knew that the mechanism with the static factory was optional.
