I've got a situation where I'm working with a legacy database that's
defined in another project and some extensions to it, written in
sqlalchemy.  I'd like to use Elixir, but there appears to be an issue
with autoloading some tables and referencing them with new ones.  Here
is a pure SQLAlchemy implementation that works: 
http://paste.turbogears.org/paste/1496

Here is the same implementation in SQLAlchemy/Elixir that fails:
http://paste.turbogears.org/paste/1497

The error is in this traceback: http://paste.turbogears.org/paste/1498

The constraint.elements list is empty when constructing the Items
object.  I'm not sure what this means, because it gets into parts of
sqlalchemy that I don't quite understand yet.

I tried working around the problem by calling setup_all() after the
autoloaded object was declared, but that did not help.

I encounter the error with Elixir 0.3.0 and 0.4.0 (latest from svn
this morning).

Is this a strict limitation of Elixir or something for which a
workaround or fix might be developed in the short term?  I appreciate
any suggestions.

Regards,
Jason
