How so? Ada abstracts by-value/reference issue away (except for some
special cases). Whether an in-out parameter is passed by reference or by
value is not a question of sematic in Ada.

This is IMO utterly wrong. The semantics of swapping element's fields is
well-defined independently on the way of access. In question in not the
semantics of, but the syntax sugar, namely an array-like indexing of the
container.
