From the Department of Insane Ideas: D on the JVM

[Gregor Richards]

No, I'm not saying somebody should do it, I'm saying I've done it.

Using NestedVM, a tool that lets you compile anything GCC supports to 
Java bytecode, I've made a modified copy of GDC that can produce native 
Java .class files from D source.

What's the use? I don't know, I only did it to have a bit of perverse fun.

Sockets and threads don't work yet, and it's not extensively tested, but 
it works enough to get a simple Hello, World! compiled.

I'll put up full documentation on using it later, just thought the NG 
might be interested in knowing it exists.
