I had to do some work to get Syntastic, which I use for syntax 
checking in Vim, to get the import paths in there from dub. I 
actually raised an issue for dub recently requesting dub to get a 
command to ouptut the import paths for you. The discussion led to 
me bineg able to finish my program.

My program can be seen here.

It looks like Dutyl currently handles this by applying eval to 
the result of 'dub describe', then doing the rest in VimL.

I might move to using Dutyl, as I am not currently running 
DScanner on my projects, and I think it's time that I did. Using 
DCD would also be nice, and having documentation on symbols would 
be nice. There is a way to implement this in Vim for mouse 
hovers. I'm not sure if Dutyl handles this already.
