The docs were written by different persons, and are hence heterogeneous and not consistent.

(kind of "there is more than one way to word it" ... well )

Even perlglossary which originates from the Camel-Book seems to have been patched afterwards.

For a trained mathematician used to an axiomatic approach it's a painful experience ... >(

So I'd strongly recommend to

• use perlglossary for definitions
• use tests to proof a thesis (runtime)
• use B::Deparse and B::Concise for visualization (compilation)

In an ideal world any other perldoc should be corrected.

I never acquired the Camel book I know it's vast but should be canonic.

It's a long time since I had a look into chromatics "Modern Perl", but it left very consistent impression. So maybe a good source, not sure if he clarifies "lists" there.

update

Modern::Perl#Lists

confusing too.
