+
+Good point.  But even then it will be premature to discuss in ARG.  The way to
+attack that problem is to hack on (some implementation of) containers, profile
+them, and experiment with possible language changes, possible compiler
+changes, etc.  Making language changes first, in the hopes that they might make
+containers efficient, won't work -- too much guesswork.

+The moral of the story is that the folks who say standards committees should
+be standardizing existing practice, rather than inventing, are right.

+
+I agree. Let GNAT figure out how to make containers usable, we have an
+enormous incentive to do that, many of our customers are seriously worried
+by the horrible performance compared to C++ and we have to do something about
+it.

+
+Especially at this stage.
