Is it really necessary to use Strings? I think a packed type, e.g. Vector or ByteString, would be much more efficient here.
Not very much if the strings are fairly short (and the list isn't too long, so there's not a big difference in cache-friendliness). If eight-bit characters aren't enough, packing the strings into UArray Int Char gives performance quite close to ByteStrings.
Of course this is only likely to be a benefit if you can move away from String entirely.
I suspect that "hamming2" would perform better then.
