If you're willing to give up the blank value for an undefined one. a hash slice will be even simpler:
@hash{split /\s+/,'1 2 3 4 5 6'} = ();

You'll need to use exists($hash{$key} to check for an element's presence instead of $hash{$key}, but that's actually faster since you skip the fetch of the value itself.
