"HOW do i guess that next would indeed be written as next and not next()...?"
perldoc -f next at your command prompt.
next is an integral flow control function in perl... it's not something special to any particular (non-core) module.

    Thanks, and what about $file->stringify ?
    I got:
    No documentation for perl function `stringify' found
    $perldoc -f stringify

      You will need to learn about the arrow operator ->, for example in perlop, and/or one of the Perl object tutorials, or maybe the Modern Perl book.

      The methods of an object are traditionally documented in the respective class documentation. In your case, that's Path::Class.

        <pedantic>To be fair, Path::Class performs some minor misdirection, and the methods of interest are found in Path::Class::Dir and Path::Class::File. But your main point is obviously correct.</pedantic>
