I love those nonsense ! How can something that is only read be unsafe!!!
And please between "dangerously unsafe containers" and "concurrent read
access containers" I think there is some room. Why always having such
strong and extreme position????

Look it is not that unusual to have a container populated for a
simulation that after initialization point does not need to be updated
but only *read*. I have many concurrent simulations like this. I would
have expected to be able to use the containers in this case.

The recurrent saying "if you don't like this, do it yourself" in
comp.lang.ada is just a big mistake for Ada as a whole. This decision is
just counter intuitive for anybody having done a bit of computer science :(

Anyway I had to say that :)

Now maybe some operations could be made safe, like those not using
cursors. For example, in Ada.Containers.Vectors:

   function Element
     (Container : Vector;
      Index     : Index_Type) return Element_Type;

Why this could not be made safe ?

Pascal.
