I think uvector only works with certain types that can be unboxed, while storablevector works with all types that instantiate Foreign.Storable.Storable. I don't know about vector. From the description of vector, I have the
One of the nice feature of uvector is the support for UArr (a :*: b). An UArr (a :*: b) can be easily (with fstU and sndU) transformed in UArr a and UArr b. uvector package also suppors Complex and Rational, however the support for these type is "hard written", using a UAProd class, and requires some boiler plate code (IMHO). I find StorableVector implementation much more simple; I would like to see it in the Haskell Platform. As for Data.Parallel, uvector and vector, it seems there is some code duplication. Both Data.Parallel and uvector, make us of a strict pair type. Such a type is also implemented in the strict package [1]. The authors are the same, so I don't understand the reason of code replication. There is also replication in the definition of the Stream data type. [1] there seems to be an error in the documentation: http://hackage.haskell.org/packages/archive/strict/0.3.2/doc/html/Data-Stric... In the description, there is: "Same as regular Haskell pairs, but (x :*: _|_) = (_|_ :*: y) = _|_" but in the synopsis, the data constructor is :!:, not :*:. Regards Manlio Perillo
