True, and in fact if you undef @array the effect is identical. See my node, above.

Try using Devel::Peek. undef @array sets MAX to -1, @array = () does not. Or use Benchmark and find out that undef @array is about twice as fast. The effect is the same, but internally, there's something entirely different going on.

Granted. But besides the speed issue, the result is effectively the same.
In the case of undef @array, @array does not actually get undefined (i.e., it still exists), just emptied, however more efficiently than with @array = ().
