yet another Map question

[Ken Gosier]

According to the Ref guide, the next method of MapIndex has prototype:

- next: (id *)key

So, would the proper way to iterate over a Map be:

id <MapIndex> mapIndex = [map begin: [self getZone]];
id key, val;
for (val=[mapIndex next: key]; [mapIndex getLoc]==Member;
     val=[mapIndex next: key])
{
   // here can make calls to key, val as regular objects:
   // [key aFunc: anArg];
   // [val aFunc: anArg];
   // etc.
}
[mapIndex drop];


TIA once again--
