An attempt to map the spec to proposed Test262 test

String.prototype.matchAll ( regexp )

Performs a regular expression match of the String representing the this value against regexp and returns an iterator. Each iteration result’s value is an Array object containing the results of the match, or null if the String did not match.

When the matchAll method is called, the following steps are taken:

  1. Let O be ? [RequireObjectCoercible][require-object-coercible](this value).
