Put it simple: T[] is a range, and T[new] is a container. They belong

Define ranges and define containers.
Yes, there is a lot common between them, because T[] supports some
subset of operations that T[new] support.
No. You see, even you who have a close perspective on the issue have
gotten confused. T[new] does not support assignment from range. So T[]
and T[new] are not in a subtyping relationship. They support subtly
different primitives.
unless I miss something
a_new[]=slice;
works just as
a[]=slice;
as in any case you have a slice on the left
a=slice; // should redefine the slice
and yes that is (correctly) not supported by T[new]
a=range;
should not be used in general imho because a slice should be a valid
range, and I don't want similar operations to have very different
results (changing the data or just changing the slice object itself).
