  use syn::Expr;
  use syn::parse::expr;
  
  // An expression surrounded by [[ ... ]].
  named!(double_bracket_expr -> Expr,

  );
  
  fn main() {
      let input = "[[ 1 + 1 ]]";
  
      let parsed = double_bracket_expr(input).expect("double bracket expr");
  
      println!("{:?}", parsed);
  }
