This is a bad application of the quote.

Most of the Lisp hackers are usually knowledgeable about analysis of algorithm complexity.

Alan Perlis comment talks about inefficiency of Lisp programs due to a lot of (meta) abstraction and indirect mapping of abstract software to hardware.

Admittedly, this particular case seems amenable to fairly straightforward algorithmic complexity analysis, but it seems to me that the lazy nature of Haskell seems to make it even harder to get a good grasp of costs involved than in a language like Lisp.
