New reserved words?

Is there any agreement on likely new reserved words for
Ada0Y?

"interface" is the only one that springs to my mind, but
that's certainly no guarantee of completeness! ;-)

I believe "overriding" is also under consideration.

You should probably take a look at Pascal Leroy's presentation to
Ada Belgium earlier this year, called "An invitation to Ada 2005"

(which I think is identical to the presentation he gave at
Ada Europe 2004 last week)

It can be found at

tml
in both Powerpoint and PDF formats.

I thought so, too. But according to the latest entry
<URL:http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/AI-00218.TXT?rev=1.15>
this is a pragma now rather than new syntax.

*oops* Forget that. Seems I'm just too stupid and read the wrong one.

<URL:http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/AI-20218.TXT?rev=1.12>

Here it is a "nonreserved keyword".

(Hope this is the right one now. If not, someone should probably give
me a short tutorial on reading the damn AIs. And I was already
wondering how fast things could change... ;-).

At this point (after the Palma de Mallorca meeting), there is likely to be
three added keywords:

    interface (AI-251)
    overriding (AI-218-3)
    synchronized (AI-345)

Whether these will be new reserved words, or whether we'll define
"unreserved keywords" is still undecided.

[Note that the last one was added very recently; it is a modifier for
interfaces, and it declares that an interfaces can only be implemented by a
task or protected type. There are also 'task' and 'protected' interfaces,
with the obvious semantics. We also approved making 'limited' interfaces
universal, in that they can be implemented by tagged, limited tagged, task,
and protected types -- pretty much everything that makes sense.]

Ada is a fairly large language already - as a trainer I'ld prefer to have
them as reserved words rather than creating a new category that has to
be explained.

That's the argument on that side. Of course, there is no real reason to
explain the difference (it's better to avoid them even if you are allowed to
reuse the names), so it seems weak to me.

The problem is that Interface is used in an Ada 83 pragma that we would want
to allow implementations to continue to support. But that's solvable.

In the end, I simply don't care much either way.

The presentation Pascal gave last week was an updated version of the
one for Ada-Belgium in March.

See the message I posted earlier tonight announcing that these versions
have been updated using Pascal's recent presentation at Ada-Europe'2004.

Enjoy...

I rather fix the code once for new keywords then have some hybrid for rest
of Ada's live.

There is also the possibility of a fourth new keyword/reserved word in 
the discussion of AI 359.  It isn't clear what it should be, and it 
might be interface also.
