Is it? What if the array you're gonna print is tie()d? Maybe it is
not now, but what if it becomes later? To share the array between
threads/processes, to store it on disk, to ...
If there was no simple and clear way to print the array with a
specific delimiter, I'd say go ahead. But there is. A way that's much
easier to understand. Without having to know about an obscure builtin
variable that affects the way arrays are interpolated into strings.
