in reply to Perl Style: Is initializing variables considered taboo?

Dont forget my @this = undef; or my %that = undef; dump either and you will see that empty array element or hash element. $this[0] = update; or $that{} = undef; That's screwed up my sql inserts so may times! i now never declare unless a variable being undef is actually integral to the function of the program. $return for example Namasté Monks!

    You should set arrays and hashes to the empty list.

    my @this = ();
    my %that = ();

      Why?

      Have you ever had a declared array or hash not contain an empty list?

        Yes, see my above comment on mod_perl.
