Re^3: Unconventional exit from while loop

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.

So the whole while statement seems redundant. Yeah. This would probably be better: `{ my( ... ) = @{ $iter->next // last }; ... redo; }` [download] At least the exit and the cause of the exit is clear.

Yeah. This would probably be better:
