Hi,

I would like to collect your thoughts about a subject:

I wonder wether it is better to use NSObject or id.
I have seen Apple is making intensive use of id in its API.
But sometimes it looks very permissive like in NSMutableDictionary -  
setObject:forKey: or
This class need to retain its entries but the method does not require  
the object in argument to responds to "retain".
I assume that they want their objects to stay as flexible as possible  
but they could require at least the NSObject protocol in the example I  
gave.

Any opinion is welcome.

Thank you,

Florent.
