RE: Two ideas for the next Ada standard (Leonid Dulman)

[dulman@ibm.net]

     As began debate concerning future of the language standard, I would
     like to do some remarks to future ADA-0x.

     1. ALIASED is more common notion then RENAMES  and  (it seams to me)
        this key word needn't.

     2. OUT parameters have such chances as IN OUT

     3. Maybe  for calling entry in SELECT statement with  DELAY to write
        in the form :

        <entry_name>(...)   WITH DELAY [UNTIL] <time>;

        ACCEPT <entry_name>(...) WITH DELAY [UNTIL] <time> DO ...   END;

        This construction will  allow to expect rendezvous  up to a given
        time moment, or given time interval.

     4. To add the subroutine parameter type ALIASED, that will  allow to
        use inside it reference to the subroutines with  " 'ACCESS " or
        " 'UNCHECKED_ACCESS" parameters.

     5. Nongeneric form of packages  DIRECT_IO and SEQUENTIAL_IO.
        Parameter RECORD_SIZE to add for  parameter's  list in procedures
        CREATE and OPEN
        (for example in form RECORD_SIZE:=<type's name>'size;).

     6. To specify use ACCESS and UNCHECKED_ACCESS attributes for aliased
        variable. Now (in basic) it is necessary to use  UNCHECKED_ACCESS
        attribute.
