Re(4): undef'ing @arrays caveat

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 = ().

@array does not actually get undefined undef can only un-define scalars, because only scalars can be not-defined. Hashes and arrays are emptied, subs and globs are destroyed. I think the manual is not clear enough about this. - Yes, I reinvent wheels. - Spam: Visit eurotraQ.	[reply]
