Good question...
In my understanding - i.e. please correct me if I'm wrong! - when
testing objects for equality the simple and the strict equality operator
are completely interchangeable.
We are not comparing values, which can be of different types (and thus
provoke 'false positives' with the simple equality operator), but
references, which have a simple, 'binary' quality: either they do point
at the same place in memory or they don't.
And two objects - by definition? - always occupy two distinct locations
in memory, completely independent of wether they are of the same type
and contain the same values.
trace({} == {});// output: false
That's why I think that when testing objects for equality, the simple
and the strict oprator will always return the same result.

Andreas,
Just sight-reading the code rather than testing it - shouldn't there
be a === or !== in there somewhere to make sure you're talking about
_exactly_ the same object rather than one which just has the same
value..?
Cheers,
Ian
