You can't.  And you don't need to.  As others pointed out already, Ruby
treats all the assignment arithmetic operators as shortcuts and invokes
the appropriate operator.  So

foo (op)= bar  <=>  foo = foo (op) bar

Where (op) is pretty much every operator you'd like to put there.
Implementing Foo#+ gives you Foo+= automatically.
