Linq and the like

D 2.x has closures, that's a good starting point, but some things are missing still:
- A built-in support of the methods LINQ accesses in AAs, Arrays, etc.
- Some external bridge, so it can be used on DBMSs too.
- Some sugar for its short syntax, you can see it here:
http://en.wikipedia.org/wiki/Language_Integrated_Query#Language_Extensions
- Multi-processing management for the parallel LINQ.

So as you can see it requires many more things, that's why it's actually useful.

I agree. And LINQ syntax is slow, so you can't use it in the inner loop of something that has to run fast. The basic idea is that D can have both high-level constructs beside keeping the low-level ones.
