Hi Monks, i'm newly registered but i've been using your site for ages. I write a lot of perl at a very basic level, (I use it for all my "data mining" at work) but i'm trying to improve my knowledge and write more concise, idiomatic code.

Anyway, i have an array, passed as reference. I want to make a new array from a slice of the referenced array, which contains only 1s or 0s depending on the value of the referenced array. In other words, i'm doing this:

my @cell_contents=map {
  if ($_) {
    1;
  } else {
    0;
  } }@$array_ref[3..10];

So if the element of the referenced array, returns as true, i want the new array element to be 1, and 0 if it returns false.

Is there a more concise way of doing this?

Thanks in advance.
