Post #101,679 by admin 5/13/03 1:14:50 PM Reply	Not J-heads. This is how Python, Perl, etc. work. If you want to increment a value in a hash, and it hasn't been set yet, scripting languages assume it to be 0. This is extremely convenient for such things. However, there is an assumption about the nature of null being made. Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."
Post #102,710 by bluke 5/20/03 4:55:14 AM Reply	Smalltalk as usual is consistent nil is the Singleton instance of UndefinedObject and all Objects are initialized to it. This simplifies many things and is very powerful, for example, when trying to print something, you don't need code that explicitly checks for nil as UndefinedObject understands how to print itself. This also allows you to add all kinds of behaviour to nil objects if needed.
