in reply to What's the best way to ask about code from an older book?

HOP has always been freely downloadable. I'm very sure there is no problem reproducing limited samples here.

Update

I followed Sleet's link to the licence agreement.

Apparently you need to cite this:

"from Higher-Order Perl by Mark Dominus, published by Morgan Kaufmann Publishers, Copyright 2005 by Elsevier Inc".

I personally would just link to the online source.
