I just watched some of the presentations, many were rather thin 
on content, but some might be informative and give food for 
thought. There was one that went in depth on move semantics and 
some challenges there that lead to new language additions that 
ought to be uneccessary IMO. Also the way they specify concepts 
is interesting to think about. There seems to be some enthusiasm 
around ranges, but there was also a presentation on a library 
called pipes that turned out to be little more than a pipe-like 
syntax for function calls. Anyway, if ranges-like APIs are 
fashionable, maybe this is a good time to innovate in that area 
by comparing and contrasting various approaches?

In case someone are interested. Here are the ones that I think 
might be of interest to some D programmers/compiler enthusiasts.

Below is a link to a presentation that goes over C++ move 
semantics and some odd cases that has resulted in some, in my 
opinion unfortunate language additions. Since there is a lot of 
talk of move semantics in the D forums, this might be informative.

Atomics with relaxed memory order is more problematic than you 
might think. Should be as relevant for D compiler devs as C++.

Another presentation of Halide, which basically just constructs 
an AST in C++, are there any bindings that are up to date?

Halide: A Language for Fast, Portable Computation on Images and 
Tensors - Alex Reinking

Might be useful for those interested in C++ interop. I guess some 
constructs could be difficult to map to D.

I don't really feel ranges is a good fit for C++, but the two 
presentations under gives an impression of two approaches. The 
last one is basically just syntactical.

Pipes: How Plumbing Can Make Your C++ Code More Expressive -

Any thoughts? My immediate thought is that C++ is soon at a level 
where it will be near impossible to pick up for beginners.

This one is also quite interesting considering the recent 
discussion of new semantics for "in" parameters. Herb Sutter 
suggests ADA-like syntax and semantics with parameter keywords 
"in", "inout", "out", "move", and "forward".
