Orange does not like Tuples

[Infiltrator]

The following code fails with no property '_expand_field_0' for tuple '(const(Class))':

import std.typecons;
import orange.serialization._;
import orange.serialization.archives._;

class Class { }

alias Tuple!(Class) Tup;

class Container { Tup[] tuples; }

void save(Container container) {
   auto archive = new XmlArchive!(char);
   auto serialiser = new Serializer(archive);
   serialiser.serialize(container);
}

I'll see what I can do.

It works (or rather doesn't) with alias Tuple!(int) Tup;, so it's not a class thing.

And also without the container:

import std.typecons;
import orange.serialization._;
import orange.serialization.archives._;

alias Tuple!(int) Tup;

void save() {
   auto archive = new XmlArchive!(char);
   auto serialiser = new Serializer(archive);
   auto tup = Tup(2);
   serialiser.serialize(tup);
}

With a shorter error message list:
