ES2020 spec-compliant shim for String.prototype.matchAll. Invoke its "shim" method to shim `String.prototype.matchAll` if it is unavailable or noncompliant.

This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment, and complies with the [spec](https://tc39.es/ecma262/#sec-string.prototype.matchall).

Most common usage:
```js
const assert = require('assert');
const matchAll = require('string.prototype.matchall');

const str = 'aabc';
const nonRegexStr = 'ab';
const globalRegex = /[ac]/g;
const nonGlobalRegex = /[bc]/i;

// non-regex arguments are coerced into a global regex
assert.deepEqual(
        [...matchAll(str, nonRegexStr)],
        [...matchAll(str, new RegExp(nonRegexStr, 'g'))]
);

assert.deepEqual([...matchAll(str, globalRegex)], [
        Object.assign(['a'], { index: 0, input: str, groups: undefined }),
        Object.assign(['a'], { index: 1, input: str, groups: undefined }),
        Object.assign(['c'], { index: 3, input: str, groups: undefined }),
]);

assert.throws(() => matchAll(str, nonGlobalRegex)); // non-global regexes throw

matchAll.shim(); // will be a no-op if not needed

// non-regex arguments are coerced into a global regex
assert.deepEqual(
        [...str.matchAll(nonRegexStr)],
        [...str.matchAll(new RegExp(nonRegexStr, 'g'))]
);

assert.deepEqual([...str.matchAll(globalRegex)], [
        Object.assign(['a'], { index: 0, input: str, groups: undefined }),
        Object.assign(['a'], { index: 1, input: str, groups: undefined }),
        Object.assign(['c'], { index: 3, input: str, groups: undefined }),
]);

assert.throws(() => matchAll(str, nonGlobalRegex)); // non-global regexes throw

```
