Excellent talk.  Gives us a good idea of the things which are missing for C# conversion and less so in general, and good ideas where to concentrate our efforts.

I have old SHA etc hashing routines in old style D, this makes me want to spend some time bringing them up to date...

Sorry I'm new to D so can anyone please explain that Destroy joke to me?

(And I have to say that this is the first -announce list I've seen where all subscribers can post! How come it's allowed here?)

It's not a D thing. It's an Andrei thing. He likes to tell people to destroy his proposals when he makes them (with the intention that people would point out any problems in them).

Just watched it over lunch and I liked this talk very much.

For transforming pieces of code I very often write Vim regex, (supports multiline with a flag) and when that is not enough, writing a Vim function does the trick.

About streams: there is some phobos support for streams, though it seems not finalized.

I wish something were done about the containers. Note that it
is very easy to write C# containers in a OOP style, based
on T[] and T[K] internally (though a concurrent hash map with
read/write locking would need to be done from scratch without
using AAs).

It is not true that Array!T is equivalent to List<T>.
Array!T wants to own their items (because it manages its own
memory), so it is only practically useable with structs.
Even duplicating the array is unsafe if the element type
is a class:

import std.stdio, std.container;

class A {
    int val;
    this(int v) {
        val = v;
    }
    ~this() {
        writeln("A destroyed");
    }
}

void func(Array!A list) {
}

void main() {
    A a = new A(3);
    Array!A list;
    list ~= a;
    writeln(a.val);    //prints 3
    func(list.dup);    //prints A destroyed
    //<-- The object cannot be used anymore, though it
    //    is still present in 'list')
    writeln(a.val);    //prints 0
}

And one cannot use RefCounted!A because RefCounted doesn't
work with classes.
I guess that RedBlackTree's suffer the same problem.

Everything stream-related which is currently in Phobos is outdated and unacceptable, so it will be replaced. A replacement is in the works, but it's not ready yet.

I want to apologize for the glaring technical error in the talk. I knew about T.init() when I was writing this but I was so focused on finding a analog for C#'s default keyword that it completely slipped my mind.

The mailing list is actually an interface to the newsgroup, where discussion has always been encouraged.

Do you know any timespans, when it probably will happen? I will be very grateful.
