Does Visula have classes or prototypes?
(Review question from VL/HCC 2006) Visula has classes. However, it does not have types – there is a difference. In dynamic typing, the “class” of an object is almost completely irrelevant. You call a method on an object, and it either works or it doesn’t. A prototype implies a “cloning” mechanism. This is not how Visula works. To construct an object, you call the “class” as a function, which executes the expressions in the class to perform initialization. Initialization is performed independently for each instantiation. This notation is shared with function calling, however it is nothing to do with prototyping.
