I agree. But those D snippets I have written are not able to show 
what the backends are or aren't able to do. Generally if you 
compile D code even with LDC2 you see a significant performance 
difference in heavy-array processing code if you compile it with 
or without -noboundscheck. I have seen this plenty of times. If 
you want we can take a look at some benchnmarks.
