Also - there are several papers which mention foldP as being part of the (prospective) implementation, but I couldn't find this in any of the modules. Has this one not been implemented yet?
Up to now, the implementation of operations in the special-purpose Prelude and the array library was essentially driven by the examples we coded so far:
http://darcs.haskell.org/packages/dph/examples/
So if we didn't actually use a function somewhere, we probably didn't implement it. Again, the motivation was to get simple examples working before making any attempt at completing the set of supported language features or library functions.
It is present here [1] -- so at least it has been implemented. 1. http://www.haskell.org/ghc/docs/latest/html/libraries/base/GHC-PArr.html#v%3... -- Roman I. Cheplyaka :: http://ro-che.info/ "Don't let school get in the way of your education." - Mark Twain
