Thank you for writing this, it seems very well done so far. And thanks for also making it available in the way that you did: I almost certainly wouldn't have played with Perl today without your book, made effortlessly available on my e-reader via Pragmatic. I'm curious why it's not available in physical copy from Pragmatic? And I'm not confident about the correct "buy" link to use to properly support the book.
One sidenote that I hate to mention, but: I couldn't figure out how to open a PR for this or even email someone who would care, but I found a code-typo on the CPAN website: it's instruction to "install via App::cpanminus" and then use with "cpanm name::module" is...an unfortunate early typo on that site.
I believe it is:

It's more valuable to me if you share and enjoy. I give away electronic versions so that it's useful, not to make money from the time I spent writing it.

Is this the page you were reading?
https://cpan.metacpan.org/modules/INSTALL.html
It's not explained on that page, but the distribution App::cpanminus installs a program called cpanm, not cpanminus (as one would expect).
