What About All Those Footnotes? (Learning Perl Objects, References & Modules)

1.2. What About All Those Footnotes?

Like Learning Perl, this book relegates some of the more esoteric items out of the way for the first reading and places those items in footnotes.[3] You should skip those the first time through and pick them up on a rereading. You will not find anything in a footnote that is needed to understand any of the later material.
