Actually it's not mine, I'm just a regular user. I don't think I could  
ever understand the finite state machine code (especially because it's  
c++), but patching the c/d1 codegen to output d2 code is easy enough ;-)

Did you mean in D2? I feared that, so I'll have to do some extra work...

Yep, that's what I want.

That's interesting, I'll have a look at it, but ragel shares big parts of  
the c/c++/d code, so as long as the C syntax works there's no need to  
change that.

Thanks for your help!
