Of course not, except sometimes - like in the special case when your array has columns where each element in the column is of the same type. Statistically, this IS almost the default case - all the aXXX() functions capable of creating arrays do return arrays of such type - but there are just enough exceptions to this that there's no guarantee that an attempt to write a general purpose function/method/prg/script/whachamacallit to handle them would be worthwhile.

The code to do most of the proposed array manipulations may be written in a dozen lines; the parameter checking may take twice as many lines, and take more than twice the time to run.
