It's not so good to have array of delegates because you will have 
a memory leaks. Delegate has permanent pointer to the object, so 
GC will never free it. As alternative, you can delete delegate 
manually, but in this case you can have problems with manual 
memory management.

So, array of delegates is possible solution, but only for VERY 
simple cases. This module solves problem with memory leaks 
because it implements weak connections (based on weak reference). 
It's easy to use, but VERY difficult to implement.

So, if you have any critical comments, please let us know. At 
least, Robert will have a chance to fix it.
