Introspection/Reflection/etc on Linux

Robert,

This stub shows the issue:

import std.stdio;
import std.range;

void main(string[] args)
  {
    string id = "somestring";
    auto rid = retro(id);
    writeln(rid.length);
  }

$: dmd  dtest.d
dtest.d(8): Error: no property 'length' for type 'Result'


I haven't applied either patch you mentioned below. Neither patch seems to
address retro() or Result...
