@h{@array} = ( );

Bruce and jd's solution are both fine and far less ugly than the FAQ. Is there a reason these solutions aren't on there and the FAQ version is using splice?	[reply]

The first code block in the FAQ says: `my %hash = map { $_, 1 } @array; # or a hash slice: @hash{ @array } = (); # or a foreach: $hash{$_} = 1 foreach ( @array );` [download] The first comment is my solution and the second is essentially the same as bruceb3's. Actually, I don't see where the FAQ suggests using splice for this.	[reply] [d/l]

Do you mean the Answer: page, rather than the FAQ? If so, take another look at the text preceding the code... "The answers in the FAQ don't modify the array in-place. In case that's what you need, you can do the following: The `splice` is needed to modify the original array in-place.	[reply] [d/l]
