Well, surpise: That was not formulated well, but there is probably no
resonable way to define equality of primitive values (i.e. those not
composed from other values) in a programming language
specification. We just have to assume that anybody knows when two
values are equal.

But for all your scorn, I note you're (again) ditching the issue I
triee to address: That the ARM is not defining equality by comparing
memory patterns.

But -- would I have expected anything else?
