This is exactly where D has the largest advantage over C#. I find 
that C# is generally good to code with, as long as you don't care 
about performance beyond avoiding big O crimes. But when you try 
to do stuff like using structs when you don't need polymorhism or 
trying to minimize allocation when working with an array, it gets 
inpractical. With D, of course you still need to put a bit more 
thought in, but it doesn't feel like the language is fighting 
your optimization efforts.
