[Haskell-cafe] Seen on reddit: or, foldl and foldr considered slightly harmful

[Johann Höchtl]

In a presentation of Guy Steele for ICFP 2009 in Edinburgh:
http://www.vimeo.com/6624203
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.

Greetings,
