Haskell encourages multiply recursive algorithms, even more than Lisp
does.  These can easily result in exponential not-so-worst cases.  In
the case of Darcs (http://darcs.net), this has resulted in unusability.

Several Haskell developers (including Simon Peyton-Jones) have
acknowledged on the Darcs lists that ghc can be expensive both at
compile-time and run-time, unless you really know what you're doing.
