Wow, so apparently we don't built on stable or beta, not because of the
compiler plugins, but because `For<i32> for i64` isn't on stable, and
`For<i32> for f64` is only on nightly. Additionally, there was a
breaking change in compiler plugins *tonight*, which I've updated for
(and am pointing at a local branch for dependencies until it gets fixed
upstream).
Sorry for the breakage folks, I know it's a pain. Update to tonights
nightly, it's now the only thing we work on, because I don't know how to
make travis go to last nights. We'll be on stable by the end of the
week.
Ok, I mean I knew that our tests wouldn't work yet because I haven't
added syntex, but that's not even the problem. Apparently the *real*
reason we don't work on stable is that `From<i32> for i64` is only
implemented on beta and `From<i32> for f64` is only nightly. I figured
there were reasons I couldn't target stable, but really????
