Well if you follow the argumentation of the talk, they are not 
relevant, none of them are enabling features, most are syntax 
sugar.

Comparing pointless feature lists really isn't that interesting, 
but figuring out how to do relevant features is.

Somewhat undecided about this. Better support for multiple return 
values would be nice, but tuple fixes most of the needs.
Kenji's full tuple proposal also included pattern matching, but 
is that more than a functional programming abbreviation of 
if-else?

We removed those from D, didn't we?

They aren't, but they are indeed nice, and we should consider 
some async/await support for D as well. For I/O bound stuff 
Fibers are performant/resource-friendly enough though.
Cheap coroutines can efficiently connect ranges with trees, very 
nice
