[rules-users] how to check reference

[Edson Tirelli]

   Yes, in 3.0.6 you will need eval. But also it is important to remember
that by default, in 3.0.6, an object will never match more than one pattern.
So in the given example, ob1 and ob2 will always be different and the check
is not needed.
   In 4.0, things are a bit different, as by default a single object may
match more than one pattern at once and we introduced the "this" keyword to
check for object identity.
