thank you for the pointer! i've had a good time reading the book
(about half way through now).  the power loops section is actually in
chapter 2 (section 4). 

the book says:
  Although power loops are elegant, they are subsumed by recursive
  proce-dures, albeit with a loss of elegance and efficiency.

i'm not sure i agree about the elegance part either...
