So what happened with this?  I have seen several references in this list 
(this is the first one I found) of someone making a good closure 
implimentation and it getting rejected.  Why are they getting rejected?  I 
think real completel closures are a requirement for any modern language.  
Even Java and C++ (!!!) will have then within a few years.
