anonymous access type

[Maciej Sobczak <see.my.homepage@gmail.com>]

Hi,

Consider a simple callback protocol:

   procedure Call (Process : not null access procedure);

This is widely used for example in the containers library (Iterate
operation).

Now, being a good citizen, I would like to explicitly stress that the
parameter is passed 'in' instead of relying on implicit mode, so let's
add the 'in' keyword where it belongs:

   procedure Call (Process : in not null access procedure);

GNAT says: "anonymous access type definition not allowed here".

I cannot find anything in the standard that would explain this. Any
references are welcome.
