Right. If you assign to _base[2], you must provide a single numeric
value. Not a one-element array.
OTOH, if you were to assign to _base[2:2] (an array slice containing
just that one element), you must provide a one-element numeric array on
the righthand side. So if there's some reason why you need to write
'{2}' and not just '2', you can accommodate that by adjusting what
you're assigning to.
