Got this trying to compile project with dependency to cpython:

.cargo/registry/src/github.com-1ecc6299db9ec823/interpolate_idents-0.1.2/src/lib.rs:1:1: 1:45 error: #[feature] may not be used on the stable release channel [E0554] .cargo/registry/src/github.com-1ecc6299db9ec823/interpolate_idents-0.1.2/src/lib.rs:1 #![feature(plugin_registrar, rustc_private)]

rust stable: rustc --version rustc 1.11.0 (9b21dcd6a 2016-08-15)

Hi! This crate only supports Rust's nightly distribution channel, as stable Rust does not support compiler plugins or the #[feature] attribute on which compiler plugins rely.

6 proposes using a special work-around that interpolate_idents could implement using the syntex crate, but I haven't gotten around to this.

I have updated the README to include this information. Sorry for the confusion! Please reopen this issue if I am misunderstanding your problem.
