John,  you implemented this method setSequence as follows:

- (void)setSequence:(NSMutableArray *)anArray
     [sequenceArray release];

     sequenceArray = [[NSMutableArray alloc] init];

     NSEnumerator *theEnumerator = [sequenceArray objectEnumerator];
     id aSymbol;
     while ( aSymbol = [theEnumerator nextObject] ) {
         if ( [aSymbol isKindOfClass: [BCSymbol class]] )
             [sequenceArray addObject: aSymbol];

I am now implementing all the accessors, and was wondering why you 
don't use this:

- (void) setSequence: (NSMutableArray *) anArray
	[anArray retain];
	[sequence release];
	sequence = anArray;

I think now the copyWithZone is available and we mark this @private, 
the latter should be enough.

Also, I suggest we use 'sequenceArray' instead of 'sequence'. Any 
objections anyone?


- Koen.
