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.
I know and this is worthwhile to add some effort to optimize
that. I was simply reminding that we should try to understand in
which case the code is not optimized and why, before jumping to
solutions.
