Sort of, yes.
Basically the behaviour of hyper-operated operators is delegated via
multimethod dispatch to the hyper-operator functions. By default the
base perl variables will expand themselves out, but the engine itself
won't enforce this, as the classes can potentially overload the
hyper-operators.
So if the multiple-dimensional aggregate provides a proper "operate
against a single scalar" method that goes multidimensionally, then
we'll do that. If it doesn't, we won't.
