Block matrices and object arrays, as general purpose S4 data structures, with automatic formatting. Matrix arrays (that is, arrays of matrices), with binary operators for succinct/convenient matrix array multiplication. Set/sequence related functions, including index/interval finding functions. Also, SQL-like select functions, analytic geometry functions, head/tail generalizations and prototype pooling/convolution functions.
