ok. thats what I wanted to confirm. I my crude code, I was doing
exactly that and was
wondering if there is some other way to make an entry without really

Maybe, perl has to do it internally but will be much more optimal than the one
I am simply forcing a value of 1
my %hash;
@hash{ @array } = ();
