I think the tie interface, PerlIO, and the fragmentary attributes syntax all three deserve a good solid treatment in print. I wouldn't write a book about any of those explicitly, but one about problems solvable by them would work.

The tie interface is the only subject adequately treated by the camel book, but the examples there only scratch the surface of what is possible with it.
