Re: Assignment Operators

It is there so that you can easily update Object members.
Take for example the following.

A := Object clone do(
	x := 5
	nonlocal := method(
		x = 10
		)
	
	local := method(
		x := 10
		)

First case you assigned `A x` a new value.
Second case you created a local variable.
