In a presentation of Guy Steele for ICFP 2009 in Edinburgh:
he "considers foldl and foldr" harmful as they hinder parallelism
because of "Process first element, then the rest" Instead he proposes
a divide and merge aproach, especially in the light of going parallel.
The slides at
[Bware: Google docs]
are somewhat geared towards Fortress, but I wonder what Haskellers
have to say about his position.
