cargo 1.33.0 (f099fe9 2019-02-12)

Can you try with a more recent version of rust? Cargo generally only supports current stable (which is 1.35 right now).

Looks like rust-lang/rust-clippy#4121

Oh, haha, I even filed that, I forgot!

Yea, I can repro that it is an issue with 1.33, and that a newer version should work. Considering that this specific case has been fixed in newer versions of rust (by rust-lang/rust#57606 I believe), I'm going to close this.

Alright thanks!
