Another reason for not making these synonymous:
Is the address of an object constant? Or might it be
remapped during the life of an object. For example,
arrays might move when they grow too big; distributed
objects may move as they transfer onto different hosts;
a persistent object might have a new address when
retrieved from backing-store).
I might want to write code such as:
$remembered_id = $obj.id;
... [ time passes ] ...
if $an_object.id == $remembered_id { ... }
If memory addresses can change over time, then we
need a more fundamental concept to act as the ID!
