It seems to be prudent to avoid talking about "the language" here.  Even
talking about JavaScript is misleading in this case, obviously.  Talking
about ECMAScript (implementations) clarifies things considerably,
because then we can look up the relevant part of the current
specification[1] (instead of speculating):

| A conforming implementation of ECMAScript is permitted to support
| program and regular expression syntax not described in this
| specification.

So the code above is not in error.
