I believe the idea is something like this: you have a class A and an 
array of instances of A.  You then want to call a method on each of the 
instances, so you grab an unbound instance of the method you want to 
call, iterate over the array and bind it successively to each member of 
the array, and call it.

Yah, in this case, it's much easier just to use 'each' or something.  
And I have to admit there have been more times that I've wished I could 
bind an arbitrary object to an unbound method...
