macro_rules! classnames {
    [@single $result:ident <<] => { ... };
    [@single $result:ident << .$str:literal $( $tail:tt )*] => { ... };
    [@single $result:ident << .$bool:ident $( $tail:tt )*] => { ... };
    [@single $result:ident << .$block:block $( $tail:tt )*] => { ... };
    [] => { ... };

assert_eq!(
  classnames![."button"."blue"],
  "button blue ".to_string(),
);

let blue = false;
let disabled = true;

assert_eq!(
  classnames![."button".blue.disabled],
  "button disabled ".to_string(),
);

let is_blue = Some("blue");
let disabled = "disabled".to_string();

assert_eq!(
  classnames![."button".{is_blue}.{&disabled}],
  "button blue disabled ",
);
