I think with the -internals idea of pushing a thingee on the stack
rather than flattening the list, the actual effect of the assingment
can easily be delayed with little cost to runtime.

Though Randal will jump all over me. It might be worthwhile enough
to kill
        sub fn { return (7,8,9,10) }

        $x = fn();      # $x == 10
