Yes this exactly what I meant. But a few hours after starting the 
topic i'm less excited about the feature. I was biased by the 
fact that i uniquely use DCD while there is of course also 
A.Bothe completion system and the default Visual D completion 
(don't know if it's been droped since the last time i used VD but 
there was setting to use Bothe's completion system in stead of 
VD's one).
