Auto merge of #594 - serde-rs:expr, r=oli-obk

No longer need `e!`

This compiles all the way back to Rust 1.7.0, and 1.6.0 fails for other reasons so I think we are clear here. The referenced issue https://github.com/rust-lang/rust/issues/19630 is still open so they must have fixed it some other way.
