I tried but it still refuses to compile:

string interfaceGuid(string ifaceName)

mixin template EXPOSE_INTERFACES(T...)(T args)

Try this:

  mixin template EXPOSE_INTERFACES(T...)

{
  void QueryInterface(ref IComponent comp, string guid)
  {
    foreach (arg; args)

and this:

      foreach (arg; T)

    {
      if (mixin(interfaceGuid(arg)) == guid) {}
    }
  }
}

component.d(6): members of template declaration expected

I am compiling it with dmd v2.058.
