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.
