How large is the data? If it fits into memory, just read the whole thing, update it, sort the keys, and then output like this:

  import std.stdio;
  import std.algorithm;

  foreach (key; aa.keys.sort) {
    writeln(key, aa[key]);
  }

Of course, you can save the sorted array in a local variable as well if you will use it again:

  auto keys = aa.keys.sort;

One great thing about programs that read and write files is that unless the data is so large that it does not fit into physical memory, you can't feel the time cost of that sort operation. :)
