Um, just because a method is associated with one class does not mean at 
all that you can't have another class with the same method name.

In fact, Smalltalk (and by extension, Squeak) use messaging to achieve 
method calls. This means that fileNamed: is a message that you send to 
the object to get back a response (a new stream in this case). You can 
send ANY object ANY message. Squeak is strongly typed but this type 
checking is not done at compile time (unlike C++ and Java). The object 
knows which messages it has a method for and which it doesn't, and will 
raise an exception if it receives a message it doesn't understand.

Hope this helps.
