asterisk users - Jan 2009 - Deprecated Realtime application, what's to be gained ???

Hi,

After seeing in "pbx/ael/ael-test/ael-test5/extensions.ael" some
interesting use case of RealTime
to store extension data (forwardto, dnd, ...) i started to play with it.

To my surprise the two applications RealTime() / RealtimeUpdate() have
been deprecated in favor
of the REALTIME() function. While it's not a big deal for the write part
since it's only a matter a
 shifting a ')' and adding a '=', the read part is quite harder
to use.

while you could simply write
          RealTime(family|col1|val1|prefix_);
          NoOp(${prefix_col2});
          NoOp(${prefix_col3});

No you have to

   Set(row="${REALTIME(family,col1,val1)}");
   Set(col2_name_pair=${CUT(row,"|",2)});
   Set(col2_value=${CUT(col2_name_pair,"=",2)});
   NoOp(${col2_value});
   Set(col3_name_pair=${CUT(row,"|",3)});
   Set(col3_value=${CUT(col2_name_pair,"=",3)});
   NoOp(${col3_value});

2 more lines per data access, and that's only you you know for sure the
column orders,
otherwise it will be more complicated,

I fail to see what's the bonus in here ...
may someone enlight me ?

In the meantime, i've made the following macro which mimic the
deprecated application:

macro app-realtime(family,fieldmatch,value,prefix) {
        Set(row="${REALTIME(${family},${fieldmatch},${value})}");
        Set(i=1);
   do:
        Set(kv=${CUT(row,\|,${i})});

        if ( ! ${ISNULL(${kv})} ) {
                Set(key=${CUT(kv,=,1)});
                Set(${prefix}${key}=${CUT(kv,=,2)});

                i=${i}+1;
                goto do;
        }
        Set(kv=);
        Set(key=);
        Set(row=);
};


If it could be of any use ..
