@bors r- Ah, yes, of course. Thanks @durka. @Manishearth r=me for the next breaking batch or whatnot. |

Why deref here, but not with the bounds?
There was a problem hiding this comment.
Its necessary (here and below) because &bounds is a &Vec while &attrs is a &ThinVec.
Right now, you cannot iterate over a &ThinVec directly; you need to deref the ThinVec to turn it into a [T] slice that you can then iterate over.

Oh, you need this merged? Cool, I'll start up a batch. (In the future, for high-pri or generally blocking/bitrotty things, please let me know that that's the case and I'll immediately initiate a breaking batch) |

I am using `ThinAttributes` rather than a vector for attributes attached to generics, since I expect almost all lifetime and types parameters to not carry any attributes.
