  • Clippy didn’t tell anything about the macro.

    warning: dereferencing a tuple pattern where every element takes a reference
      --> src/lib.rs:13:9

    13 |         &Some(ref cons_rc) => {
       |         ^^^^^^^^^^^^^^^^^^

       = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_borrowed_reference
       = note: `#[warn(clippy::needless_borrowed_reference)]` on by default

    13 -         &Some(ref cons_rc) => {
    13 +         Some(cons_rc) => {
       |
    

    To put #[allow(this_linting_rule)] like this:

        [ $x:expr, $( $y:expr ),* ] => {
    	#[allow(unused_assignments)]
    	{
    

    I got error[E0658]: attributes on expressions are experimental.

    To put it like this:

    #[macro_export]
    #[allow(unused_assignments)]
    macro_rules! list {
        () => {
    	None
    

    It doesn’t work.
