[Newbies] Collection>>Includes:...

[florent trolat]

Hi,

I've define an '=' message for an oject and I want to use this object in 
a Collection.

I've seen that 'incudes:' message use '=' or not '==' and it's not fun 
for me!

I think that '=' message is to compare two objects and  '==' to know if  
the two object are one!

So for me 'includes:' must use '==' or not '='...

May be I have not understand something...

Thanks to help me....
