There aren't a lot of languages that combine functional programming/generics & OO together quite so extensively. There's a lot of power you can unlock there if you can just manage the cognitive load of the syntax.

I really like how D combines these two. The functional programming tools are a lot easier to use than C++ and a lot more practical than Haskell or OCaml. I absolutely adore the idea of purity in D: no side effects. That's all it should be, really. What this means is that it allows you to write pure functions in dirty, imperative ways as long as all the mutation is confined to the function and doesn't leak out.

I really like it.

D is a very nice language, just needs a better GC implementation and more community love.

D is, in a lot of ways, C++ without the syntactical compatibility with C.

[jordigh]

Absolutely agreed.

D is kind of the C++ I always wanted. It's familiar, I can see the C++ lineage, and it's so much nicer to write than C++.

I'm currently having fun writing Advent of Code in D:
