That doesn't really capture the notion. I would expect block_array()
to let me build up any blocked array (e.g. [[A, B], [C, D]]) like
bmat() already does, not just blocks along a "notional diagonal". I
suggest we bow to Matlab's precedent. It apparently has not caused
many problems in their community.
