Yes you are :) I'll give this a try at repoing, and let you know what I find.

Subject: [IronPython] Silverlight wierdness with __slots__

Looks like I've been making work for you folks tonight :(

I seem to have encountered some trouble with slots, but the very
strange thing is, it only seems to happen in silverlight. I run over
this code a lot in my test suite, and it passes (running with wpf.) If
I comment out the __slots__ = ('blocks',) it works. Any idea if I'm
doing something wrong or if it's a problem in IronPython?

I thought perhaps I'm mixing assemblies by mistake, but I copied all
IronPython 2.0b3 .dlls from the silverlight folder, right into my .xap

Here's the traceback. Code for the offending class hierarchy is
available if it will be helpful.

I'm trying to figure out why I'm having so many issues I never see
outside of silverlight.
