Yes.  Better to concentrate on things D *can* enable, like a 
great performance programming experience.

D appeals to me primarily because it lets me write simpler 
performant code.  It regularly opens the door to better 
perf/complexity ratios than C++ for example.  This is 
particularly important in markets where even small performance 
gains bring large economic benefits, where novel code is 

OTOH, if your value add is more about quickly 
assembling/rearranging existing components that are sufficiently 
peformant in themselves and in combination, well, by all means, 
carry on!
