Allowing value objects (and perhaps mutable object) to define operators
means giving up some invariants, similar to proxies which can have
incoherent has/get etc.
So I'm not sure what you are waiting for. A badly written user-defined
value object? Those may be easy to cough up in order to complain about
extensibility, but the whole point of value objects is to avoid hardcoding.
If you want an int64 spec/impl to evaluate, that'll take a bit longer.

Someone who insists on using === only can convert from one numeric type
to another:
js> int64(0) === 0L
true
Of course you have to beware of values that convert lossily, but for 0,
1, ... N, we have == and I think it ought to work.
