Or maybe not. We need some way of getting the keys of just the first dimension, and maybe .keys is that, on the model of Perl 5, where all multidims are really XoX in form, and .keys only ever gives you the top level. Then ^%hash and %hash.keys would mean the same thing only for 1-dimensional hashes. Likewise for arrays. Larry
