-# Notes:
-# - -Zno-trans has been deprecated, and will only be available with the
-#   nightly compiler starting with rust 1.19.  Using "cargo check" is the
-#   preferred alternative, though it currently has some limitations. See:
-#
-#       - Unstable flags removed:
-#         https://github.com/rust-lang/rust/issues/31847
-#
-#       - Cargo check added in rust 1.16:
-#         https://github.com/rust-lang/cargo/pull/3296 (based on original
-#         "cargo check" addon https://github.com/rsolomo/cargo-check/)
-#
-#       - RLS was recently released
-#         (https://github.com/rust-lang-nursery/rls).  It's unclear to me if
-#         this will perform full-linting that could replace this or not.
-#
-#       - "cargo check" ignores #[test]:
-#         https://github.com/rust-lang/cargo/issues/3431
-#
-#       - "cargo check" will not re-issue errors/warnings if nothing has
-#         changed.  This generally should not be a problem since on-save
-#         syntax only runs after the file has been saved which updates the
-#         timestamp, but it's something to be careful about.  See:
-#         https://github.com/rust-lang/cargo/issues/3624
-#
-# - -Zno-trans prevents some warnings and errors from being generated. For
-#   example, see const-err.rs.  "cargo check" does not have this problem.
-#   Other issues:
-#       - Errors generated by compiling an extern crate do not not output as
