Would we be able to end these interminable debates if we just agree that 
we all know how it works, and it isn't important to come up with a 
simple name for what it is? It seems clear to me that "value" and 
"reference" are wildly vague terms, used slightly differently by each 
language, and by different people even in the same language if they have 
different perspectives.

Can't we just stop? :)
