Don't really like either proposal -- because they seem like hacks
rather than a serious approach to the problem. Also, Common Lisp is
already over-bloated, it just doesn't need creeping featurism -- but
rather a trimming down. After all -- these proposals simply relieve the
user of the very minor chore of making displaced arrays for the rare
instances where that is the natural thing to do -- no real value is
added, but there is a cost in complexity, and possibly performance.
The truth is that if you really want to do multi-dimensioned array
manipulation, you really do want something like APL, or close to it.
Implementing an array calculus -- like APL -- is quite doable (I have
something close to that floating around), and is the right way to go for
heavy array users, but I don't think that functionality needs to be
built into the language.
