On second thought, if the former approach does work in IE 10 and 11, or if
you do know another approach that works there, please tell. I can then test
whether it works in previous versions also, and we may eventually not only
have a way to work around the recent Microsoft nonsense, but also to detect
support without the need for a call as constructor (which is also needed for
the ES Matrix).
