Visual-D is not Boost-licensed (I think this would be possible to 
change)
Mono-D is written in C#, as you mentioned
Pegged may eventually become standard, if it will be performance 
optimized and a bit more customizable
Dscanner(https://github.com/Hackerpilot/Dscanner) from Brian 
Schott is pretty good, too.
SDC is another nice option
DIL (http://code.google.com/p/dil/) is very nice but GPL

I plan to try using Pegged inside my DCT project. Probably that 
will require huge modifications though...
