The only text that comes to mind is the almost-universally-liked Mastering Algorithms with Perl. (The only person I've known to dislike it is the enigmatic Abigail, who has high expectations.)

You wouldn't do badly with decent books about programming, whether Design Patterns, Code Complete, or even Extreme Programming Explained. I'm not aware of any books discussing functional programming design, at least from a language-neutral point of view, but there are bound to be a couple out there worth your time.

Having just used closures and recursion to solve a rather nasty puzzle, I'm a big believer in mixing different techniques when appropriate.
