An "object" is by definition a "region of data storage in the execution
environment, the contents of which can represent values".

A "value" is by definition the "precise meaning of the contents of an
object when interpreted as having a specific type".  (IMHO this is a
slightly flawed definition; it doesn't cover the value that results from
evaluating an expression.  But the definition of "expression" does say
that it specifies computation of a value.)

I'm not sure what you intended to add to the discussion.
