[Haskell-cafe] Array, Vector, Bytestring

[Clark Gaebel]

That's absolutely true. Wrappers around vector for your multidimensional
access is probably best, but Vectors of Vectors are usually easier.

But again, you're right. Multidimensional access is a pain. If it's a
"matrix" of numerical values, you could take a look at 'hmatrix'.
