Thanks for your input! What do you mean by "short circuit"? Also, the difference between your is_perfect_square sub and mine is that mine is much more clear. I can afford the extra line for a bit of clarity.

    It means that the part after || will only be evaluated if it is needed know the result of the operator. In the case of the or-operator the second half is redundant if the first is true, since the total will be true no matter what the second part is.

      I don't really understand how that is a problem. If the first part passes, then I want it to return true, and I truly don't care what the second part is. I guess I see how that's redundant, though.
