[Numpy-discussion] Interest to port Numpy to Haskell, with Accelerate/Repa to do the crunching?

[Compl Yue]

Hi Matthew,

I hate to say I'm still a noob in the implementation details of Numpy, I 
just got an interpreter for sth else working, and suddenly realized it 
can make seemingly better magic methods in Python spirit.

Repa and Accelerate per my learning so far, are focused on loop-fusion, 
i.e. optimization after all intended computations have been expressed 
and composed together, this seems some different from Numpy/Pandas 
tradition to implement doable things ex ante, and let the users do 
things interactively  ad-hoc. That said, so I feel Repa will do composed 
computations more speedy, once properly organized. And with Accelerate, 
since it does GPU natively, I do feel a sure thing for it to excel CPU 
implementations.

btw I'm not a native English speaker, please don't hesitate to ask me to 
make myself clearer in my wordings, I'm aware of my flaws in English skills.

btw I'm a believer that Brain-Computer-Interface ought to happen sooner, 
especially non-intrusive ones, I can't wait to program such interfaces 
for great good and fun. I see you are pioneering in this area, take my 
admiring, and I started following you on github, looking forward to hear 
from you more.

btw I'm behind China's Great Fire Wall, access to some western sites are 
banned badly at times, that will explain why I can be unresponsive some 
times.

Cheers,

Compl
