| You can declare a class in one of two ways. The most familiar syntax for class declaration ends in a semicolon. The rest of the file after the declaration defines the class. With this syntax there can be only one class or module declaration in a file. class Heart::Gold; # class definition follows . . .
The other syntax for class declaration wraps the definition in a block. You can have as many of these as you like in a file, and even embed one class within the block of another. class Heart::Gold { # class definition enclosed . . . }
With a file definition, all code that follows the class declaration is defined in the Heart::Gold namespace. With a block definition, everything within the block is defined in the class's namespace. To create a new object from a class, simply call its new method. The default new method in the universal base class Object creates and initializes an object. $ship = Heart::Gold.new(length => 150);
There's a shortcut for typed variables so you don't have to give the name of the class twice: my Heart::Gold $ship .= new(length => 150);
