[Message part 1 (text/plain, inline)]
Right now there are no library functions for folding over arrays (or
bytevectors, etc.) This implements them. fold-all produces a single value
regardless of the number of dimensions of the array; it is implemented on
top of array-for-each. array-fold produces an array of rank n-1, where n is
the rank of the original array.

I'll write up documentation if the code looks acceptable.

Regards,
Jez

Ah, I reread my code and realized that I could compare array-types using
eq? instead of equals?. I'll change that once I get feedback on the current
patch.
