Until this gets added, you can use this pattern to get the
same effect in your code:
dest: insert/part (make binary! len) (at src start) len
where start and len are numeric offsets, or:
len: (length? start) - (length? end)
dest: insert/part (make binary! len) start end
where start and end are series positions. Both versions do
direct source-to-dest copying, making them as efficient as
your suggestions.
