• we should disallow use of backticks without need:

  let col = `crimson`; // bad, use single quotes

• we should allow the lack of space between one-line class members:

  class Shape {
    #x; // it's ok not to have an empty line between #x and #y 
    #y;
  
    constructor(x, y) {
      …
    }
  }
