There is no such beast.  But I think we should have it.

For now maybe something like mew Uint8List(4)..setRange(0, 4, [...]).

Ugly I know

On List in core there is a from(Iterable other) constructor. It could make sense
to add that to typeddata.

Agree- I've seen unrelated bugs come through where people are using the
.fromList syntax, so it's in use today.
