Anyone got ideas on how to get sort() working in the *return*

//------------
ushort[] draw8Numbers()

import std.meta : aliasSeqOf;

import std.random : randomShuffle;
randomShuffle(numbers);

`sort` returns a SortedRange of ushorts, not an array of
ushorts. Make it:
```
import std.array : array;
return sort(numbers.take(8)).array;
```
--Ryan
Use .release to obtain the underlying array. No need to do
another allocation!
```
numbers.take(8).sort.release;
```
