I would challenge this statement somewhat. I do high-performance
programming in C++. I don't expect D compilers to generate faster code
than C++, but to rather that they will achieve parity.
What I do expect is that D will make it significantly easier to write
and maintain this fast code. That is worth quite a bit. Developer time
is important even when writing high-performance code.
My experience in tuning D code for speed is that if you write "C++" code in D,
you will get the same performance as C++. However, D makes it a *lot* easier to
reorganize/refactor code to try and make it run faster, and this makes for
better algorithms and hence faster code.
For example, should I pass an object around by ref or by value? In C++, I've got
to convert all my -> to . or vice versa, throughout the code. With D, I just
change the alias declaration.
