This macro allows for general pattern matching of arrays. Binds x ... to the first items of arr and xs to the remaining subarray and executes the body xpr . xprs in this context. A more featurefull solution would be to use the bindings module:

(use bindings)
(bind-table-add! array?
                 array-length
                 (lambda (arr item) (array-item item arr))
                 (lambda (arr item) (array-drop item arr)))

Then you can use bind and friends and freely mix arrays with other sequence types.
