I've set up a live stream for this. No guarantees of the quality, it will be audio + slideshow.

Waiting for people to arrive, so probably won't start until at least 6:30.

Great talk!

Thanks!


Regarding the inferred attribute problem with the concepts like Straw-man usage, this should not be a problem with my attributes DIP, since all special attributes become normal attributes and you could just have an AliasSeq of the required values.

Maybe I'm misunderstanding you, but my concern is that something like this:

struct StrawmanRange(T)
{
  ...
  void popFront() {}
}

So popFront would be inferred to be pure, @safe, and nothrow. However, since really we want to only do what was specified, we don't want the compiler inferring this. More specifically, I wouldn't want the `implements` function generating requirements that a suitable range struct must have @safe nothrow pure popFront. I don't think introspection can tell whether the attributes were specified or inferred.

I don't see how being able to combine attributes is going to be able to prevent compiler inference of them. Or maybe I am missing something?
