I agree that having a native D backend is a good thing. In fact, 
I'd very much like to see WebAssembly/asm.js codegen built around 
a backend that create compact builds since download size is an 
issue. Which is a different kind of "performance".

I just don't see how I could use the current backend to achieve 
it. Maybe with your experience you could at some point in the 
future lay the foundation for a new a free backend, that is more 
minimalistic than LLVM, but that also could be used for the web?
