Because there's no logic in it! Why is the most compelling example of using
a spoon to eat with it and not digging with it? You could, but you normally
don't. Why? Because everyone sees that a shovel would be much faster and
besides you wouldn't look as silly ;)
I think that inuitively the '+'-operator could be used to add or concatenate
two objects of the same type.
BTW: Everyone against op-overl. would have to live without the current
"hello" + " world" construct, but I guess you can.. :)
