Re^3: Unconventional exit from while loop

[hdb]

This is what has caused me to ask the question in the first place. The condition in while always returns true until the iterator is exhausted, but before while has a chance to exit, last takes over. So the whole while statement seems redundant.

Yeah. This would probably be better:

{
    my( ... ) = @{ $iter->next // last };
    ...
    redo;
}

At least the exit and the cause of the exit is clear.
