Thanks Juan... I could still use some help on this.

I was able to get a bit further by wrapping ContextPart trace: around
the self halt in OMeta2Base apply: and have attached the relevant
output.  As it goes up the handler chain, it runs into a nil which I'm
believe is the issue.  If it is, I don't understand why it's nil
(isn't an empty block, as used in ometaOr: effectively a noop?)  If it
isn't, then I'm at a loss as to what's going on...

Thanks,
Phil
