match on Result<T,E> and return the error

[pythonesque]

Did you mean to use try! ? :)

Related: matching and then panic!("{}", err) instead of result.unwrap()

Doesn't macro expansion run before lints? That might throw a spanner in the works, since try! and direct matching would become indistinguishable.

[pythonesque]

Hm. I think try! is actually a little different from this now (it does From<Error> conversion), so this might provide a way to distinguish between it and someone accidentally returning.
