RE: "multiple inheritence" / behavior

[Mondragon, Ian]

use a @protocol - that's exactly what they're for.  if you want all of your
classes to respond to everyoneDoThis and everyoneDoThat...

--- SecretMethods.h ---

@protocol

- (void)everyoneDoThis;
- (void)everyoneDoThat;

@end

--- end ---

then in each of your non-related classes, just declare them like so:

--- WhateverClass.h ---

@interface WhateverClass <SecretMethods>

--- end ---

then implement the methods.

problem solved.  another hoo-rah for objc.
