in reply to How to get 0 to initialize a value

When I run your code I do not get the warnings you mention, but this line:
my $first_novel = $novel_list->[$first_book];
does give a warning fatal error (praise be to monk of anomaly). @novel_list is a plain array not an array reference - it should be:
my $first_novel = $novel_list[$first_book];

    ... this line:

    my $first_novel = $novel_list->[$first_book];

    does give a warning.

    It does not give a warning, it fails to compile due to a fatal error from a stricture that was (wisely!) enabled (use strict; statement at start of code; see strict). You may say this is a trivial difference, but a warning is not fatal — unless you explicitly make it so!
