I was just wondering if "www.world-of-digitals.com" is a legitmate source for the Moritz Lenz book "Perl 6 Fundamentals". They've got a PDF up available for free download:
https://www.world-of-digitals.com/en/moritz-lenz-perl-6-fundamentals-ebook-pdf But I also see that Apress is trying to sell an ebook version of it, which makes me wonder if the free download is a pirated version: https://www.apress.com/us/book/9781484228982 But on the other hand if "world-of-digitals" is a pirate site, I would think I'd find someone complaining about that.
