Thanks for the review! I noticed that there is a whole section about "vector pattern matching" here: https://github.com/rust-lang/rust/blob/master/src/librustc_trans/trans/_match.rs#L141 - it probably needs a makeover, but I don't want to just blindly replace "vector" by "array" or "slice"...

Ah it's probably ok to basically leave as-is, I have a feeling most of it is about either slices or arrays, not necessarily vectors, but I'm also not super familiar with it.
