Description

GHC now tries to push a few things (I'm not sure what exactly) into `runRW#` blocks. I guess this is sometimes good? But when inlining doesn't happen, it's rather bad, because our trick of pulling constructors out of those blocks is now being defeated. Ugh! I'm not sure exactly what to do about this, aside from complaining to GHC HQ.
