+  A RegExp searchValue's Symbol.replace can be called instead of the next steps of replaceAll
+info: |
+  String.prototype.replaceAll ( searchValue, replaceValue )
+
+  1. Let O be RequireObjectCoercible(this value).
+  2. If searchValue is neither undefined nor null, then
+    a. Let isRegExp be ? IsRegExp(searchString).
+    b. If isRegExp is true, then
+      i. Let flags be ? Get(searchValue, "flags").
+      ii. Perform ? RequireObjectCoercible(flags).
+      iii. If ? ToString(flags) does not contain "g", throw a TypeError exception.
+    c. Let replacer be ? GetMethod(searchValue, @@replace).
+    d. If replacer is not undefined, then
+      i. Return ? Call(replacer, searchValue, « O, replaceValue »).
+  3. Let string be ? ToString(O).
+  4. Let searchString be ? ToString(searchValue).
