TMI: Bug hunting

I'm back from vacation, which means Daily TMI is back! In my confused post-vacation state, I decided I'd better set aside destructors (the last thing I worked on), as they're a new feature, and focus on fixing bugs in the compiler for a little while. There's a general consensus we need to do a sprint of fixing-bugs-not-adding-features, as the bugs seem to be piling up.
