Re: ::'s role in strings

I do not know, what this book is trying to say, either. Yet I think, :: does have more meanings in addition to those you mentioned, at least in OO-context. AFAIK,

Animal->foo()
[download]

is the same like

Animal::foo("Animal")
[download]

Now, if Dog is an Animal, and has no own implementation of the foo()-method,

Dog->foo()
[download]

is the same as ~~Dog::foo("Animal")~~ update Animal::foo("Dog") (thanks to ikegami)

Maybe you can clarify your question a little bit further.

As to your p.s., I know :: as the 'scope resolution operator', but I don't know whether this name is really very common in the Perl community.

You got it backwards `Dog::foo("Animal")` should be `Animal::foo("Dog")`	[reply] [d/l] [select]

Your first two examples are not necessarily equivalent. Function invocation uses a very different lookup mechanism from method dispatch. The postfix double colons exist to disambiguate classnames from barewords in the parser.	[reply]
