I'm not sure why sort(vars) doesn't work...
Basically, char[] is a (mutable) string. Since strings in D are
treated as UTF, hasLength!(char[]) is actually false. Each
"character" can actually be multiple bytes long, so it sort of
makes sense. If you were to allow sorting of strings, then
characters would be broken apart in the sorting process... so it
doesn't do what you would expect it to do in those cases.
So, the way around it is to just treat it as numbers (using
std.string.representation, as bearophile pointed out) and sort it
that way.
