Here’s how my Friday night is going:

def signin
if should_not_sign_user_in?(stuff)
return redirect_to :nope
end
# signin logic
end

The guard says I shouldn’t sign the user in. It logs the details of why. I read the logs; they’re all correct. It logs the return value, which is false, and the user gets signed in anyway.

Wat.

There’s a return and a redirect there!

This is only happening on the QA server, too, so something fishy is going on.
