I can confirm, for what it's worth, that it was the conscious intent of
the language designers to permit non-scalar (and non-access) parameters
to be passed by either copy or reference, at the option of the implementor.
If there is anything currently in the RM that prohibits that, I'm not aware
of it; should you know of any such statement, please bring it to the
attention of the Ada Board, so that they can fix it.
