I'm pretty sure there's a market for D on consoles and mobile gaming. This is the first thing I get asked every time I suggest using D at work (we mainly do casual games while also porting AAA titles with a few internal engines).

So far I've only been successful with a few shell scripts calling into the tools of the console's SDK doing mass reflection on 75k shader object files among other things. Yet I do half of my home projects in D and absolutely love it.

I think getting D to interopt with more existing code in all of C#, Java and Objective-C as well as on both mobile devices and game consoles will greatly help its adoption with the "oh its just another library we add to our existing codebase" factor which has tremendously helped Clojure take off.

This means D could make it easy to extend both JVM and CLR applications with lighting fast code while getting free access to their respective ecosystems. I for one would love to use D instead of C# to write Unity code.

Clojure isn't really a fair comparison. Clojure hasn't got low-level interop with all those things, just JVM, and that interop is bought at the cost of closely tying Clojure to JVM. I don't think D can be changed in all the basic ways that would be required to give it the same level of integration with JVM, and that would also basically mean abandoning the entire standard library. JVM's difficulties integrating with things other than JVM aren't something I imagine D can really solve.

I meant things such as extern(C#) and extern(Java) to work the same way extern(C) and extern(C++) do now.

I don't see the point of compiling D to JVM or CLR byte-code for all the efforts it would involve, but rather the CLR or JVM load native code written in D and have each call into each other easily.

Say I can't reach the performance I want in C# and I want to write that part of the system in D and load it in Unity and then call into native D code from there. Without having to mess with the CLR implementation details. That would definitely allow people to try it out and integrate it gradually until it has completely taken over.
