I've also been playing with getting a Intellij IDEA plugin up but 
it utilises DScanner. The only issue I'm having right now is for 
some reason its adding two elements to the Psi's tree instead of 
just one. Where the second has correct data but first is the 
correct type.
Not to mention getting dscanner to output the correct line 
number/index ext. Fun times.
