E0302: 'this' parameter not allowed when destructuring

TypeScript allows you to explicitly declare the this parameter. It is a syntax error to destructure the this parameter or to include the this parameter when destructuring another parameter:

function swapRings([this, hers]) {
  return [hers, his];

let newRings = swapRings([hisRing, herRing]);

To fix this error, name the parameter something other than this:

function swapRings([his, hers]) {
  return [hers, his];

Introduced in quick-lint-js version 2.10.0.
