Hmm…this is an interesting case. It's possible that we've not fully looked into calling super with explicit block args. Can you see if this can be reduced to a simple, self-contained example? Either way, it would be good to have a Trac ticket for this issue.

Thanks!

Control tower by itself seems to be doing Great. However, if I attempt to load sinatra for the never-been-done-before hello world example, I get this:
