Nice package!

An idea for sourceVector is to use the streaming interface [1]. It would be nice if GHC could fuse the array with sourceVector, avoiding to produce the array in the first place, but I'm not going to hold my breath =).

I looked over it and decided to simply go with head/tail (not sure why I used the index thing... head/tail is so much more "functional"). That should still get some fusion benefit, right, since it all uses streams under the hood?

I'm almost sure that it won't fuse using head and tail, but YMMV.

Okay then. I just implemented the stream version; its at the git repository but I probably won't release for a few more days since I want to expand the testsuite.
