Doh.. Your original is fine, and you've fixed the pdf at http://modernperlbooks.com/drafts/modern_perl/modern_perl_2011_2012_draft.pdf

The pdf I downloaded from there earlier did not have the "0" ( here's a screen grab of what I saw http://imgur.com/kuvZt note the missing 0)

So when I didn't see the "0" I thought C<0> was some sort of anchoring markup which didn't produce any output. Now that I know better, I know my "fix" is junk. I'll build the pdf from git from now on.
