Using `@hash{ @array } = (1) x @array` would be more idiomatic. There's no need to get map involved since you really aren't changing the values of the array at all. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l]

I usually use `$hash{$_} = 1 for @array;` instead.	[reply] [d/l]
