Darcs is written in the obscure boutique language Haskel.  Haskel is a 
very high level language, which means that you specify problems at a 
level higher than the precise algorithm, which means that Haskel may 
implement an exponential or high order polynomial time or storage space 
algorithm, which runs fine on toy academic and test tasks, but never 
completes on real world tasks.

Such very high level languages will never produce usable software unless 
they report the order of the algorithm.
