Again, a feature in mapping document 2, very controversial,
bit the dust. Basic arguments against this are that
a) it would cause significant changes in the RM (ho ho,
that was back in the days when we fooled ourselves
into thinking this would not happen anyway).
b) it seemed to open up too big a door in the typing model,
and that is still a valid objection. However, this is
definitely a reasonable item to rediscuss.

Shrug, no opinion, seems unimportant to me.

The latest version of GNAT on some targets implements a
restricted run time that roughly corresponds to the Ravenscar
model, since this seems to be what people want. There is no
likelihood of doing JUST the above case, since so far there
is no demand.

Our approach here is to optimize simple protected types.
SO's as such are not of particular interest to us.

We have in fact done an experimental version of this port, and
it is being beta tested now. No commitments for the future
support of this port have been made, but it is a good guess
that it will become real sometime in the future.

Sorry, for this you have to be a supported customer :-) :-)
