For "Prior Work", I'd say the most obvious thing to cite is the 
shortened syntax for `in`, `out`, and `invariant` contracts:

```d
// Short versions
in (n > 0);
out (ret; ret !is null);
invariant (start <= end);

// Long versions
in { assert(n > 0); }
out (ret) { assert(ret !is null); }
invariant { assert( start <= end); }
```

This is a pretty cool idea.
unittest being one of the big win of D, why not have more of it.
