Re^2: Another reason for perl beginners to read perldocs

A good rule of thumb is, if you have 2 or more loops, you might use a label. You need a label if you want to exit an outer loop from an inner loop :)

Another good rule of thumb is, if you have 2 or more loops, start turning inner loops into function calls :)

I would strengthen your first rule of thumb to: "You should only use a label if you have two or more nested loops and need to exit from an inner loop to an outer loop". I very much agree with your second rule except I would widen it to include any nested code: "If you have nested flow control blocks consider moving inner blocks into functions".
