Cursor types are not tagged, therefore prefixed notation does not work
for them. It has to be "Position := [Package_Name.]Next (Position)".
But you don't need to do that at all.
Also, you seem to imply that abbreviating cursor operations is a
design goal of yours. I fail to understand why. My design goals
would rather be legibility and maintainability and I very seldom use
"use" clauses.

Yes, using Ada.Containers.Hashed_Sets.Iterate. You pass an access to
a procedure to Iterate and Iterate calls your procedure once for every
element in the container, passing the cursor value.
However in the present case, I advise against iterating over any
container. My small example uses only Find, Insert, and
Replace_Element for each word in the input file; there is no iteration
over a container.
