in thread Flip-flop reset?

Nice idea sgifford. I think that what I may do is actually put the newline at the end
foreach (@arr, "\n") {
They should work identically, as far as I can tell, but I can verify that the operator flops before leaving the subroutine now. This should work for both cases of input as I stated above.

Thanks for everyone's input.

    That will only work if you are certain nothing in your for loop will bail out early, including something throwing an exception that's caught by a caller of your sub. Putting the dummy "\n" at the beginning of the loop is safer.
