Question

In a loop, I have several conditions and if the condition is not satisfied, I exit out of the loop using last syntax.

while (condition) {
    if (possibility 1) {
        ...
        last;
    }

    if (possibility 2) {
        if (possibility 3) {
            ...
            last;
        }
        ...
        last;
    }
}

After I come out of the loop, I need to know whether I used last to exit, or the condition just did not hold true any more. One way of doing that is to write a if statement that negates all the possibilities.

I am looking for some easier/more elegant way to do this.

Is there some Perl variable that stores the information that we exited out of the loop due to last? Or do I need to maintain such a variable myself?

Answer 1

You pretty much just need to set a flag before you exit
