An object is a referent that knows which class it belongs to.
A class is a package that provides methods. If a package fails to provide a method, the base classes as listed in @ISA are searched, depth first.
A method is a subroutine that expects an invocant (an object reference or, for static methods, a package name) as the first argument.
- bless ref [
,classname ] Turns the referent ref into an object in classname (default is the current package). Returns the reference.
- invocant->method [
(parameters)] Calls the named method.
- method invocant [ parameters ]
Provides an alternative way of calling a method, using the sometimes ambiguous indirect object syntax.
