I'll just add, haddock + hoogle has done a lot remove the learn all

* OpenCLRaw for me is a dead one. The main developer make no reply.
* OpenCL, HsOpenCL and hopencl are the packages more suitable tu fuse.
I think that the best aproach is to use the OpenCL standard API as it
is, and let more libraries that use *opencl* packages decide what
high-level API offer. I like the Accelerate approach to show a better
API to users.
I currently working in the application that need the use of OpenCL.
The package that I develop offers all I need for now, so I not
upgrading it, only bugs or requested features for users. But in the
future I plan for two options: a) change to the *opencl* package that
gets mainstream, or b) continue with own OpenCL package because it

As Jason Dagit say, I put the stdcall call convention option in OpenCL
Other issues to solve,
How to compile in hackage server to generate documentation online?
opencl.h isn't in the server so I getting errors.
