Ahh, so that explains it. Thanks for the quick update.
Re-listening to the course video, it's clearly stated within the first 30 seconds that 4 functions are going to be covered: 2 that are available in 10.3 and the other two "Upcoming Features". I think I got thrown off because the presenter says "you will see them in the next release of the Wolfram Language" so I assumed (that almost always gets me in trouble) 11.x would qualify as next release.
Knowing now that this feature is forthcoming and not expected to work at this time, I'll anxiously be watching out for all coming releases. Again, thanks for the quick response.
Regards.
