This breaks some code that looked like `1 as u32 + 2`, because now `+` is part of the type grammar. Change it to `(1 as u32) + 2`. Part of rust-lang#12778. [breaking-change]

I talked with @pcwalton in person about this, and we agree that this needs an RFC first because it's changing the syntax of the language. |

Closing until we see an rfc. |
