Don't do this, because it's not what you think. It's not actually 
calling std.algorithm.sort, but the builtin array sort property. This 
will be going away soon.

Annoyingly, because of autodecoding, you have to cast to ubytes via 
representation to do it the "proper" way:

import std.string: representation, assumeUTF;
import std.algorithm: sort;

auto bytes = line.representation.dup;
bytes.sort;
auto result = bytes.assumeUTF; // result is now char[]
