Stephanie,

In ruby, we don't assign to an instance as you mentioned, we assign to a
variable that can hold any type. We therefore can't override the
assignment operator.

BUT you can override an assignment operation.. such as

class Foo
def bar= (val)
@bar = val
p "I am assigning #{val} to @bar"
end

hth
