[INFO] [stderr]     = note: this usage of panic!() is deprecated; it will be a hard error in Rust 2021

[INFO] [stderr]     = note: the panic!() macro supports formatting, so there's no need for the format!() macro here
[INFO] [stderr]     = note: this warning originates in the macro `simple_match` (in Nightly builds, run with -Z macro-backtrace for more info)
