What are best practices for working with perl -d debugger?

When working with the Perl debugger (perl -d), following best practices can enhance your debugging experience and improve the efficiency of your development process. Here are some recommendations:

• Familiarize Yourself with Commands: Understand essential commands like 'n' (next), 's' (step), and 'p' (print) to navigate through your code efficiently.
• Use Breakpoints Wisely: Set breakpoints using the 'b' command to pause execution at critical points, allowing you to examine the state of the program.
• Inspect Variables: Use the 'p' command to print out variable values at different stages of execution. This helps in tracking down problematic values.
• Leverage the 'h' Command: Whenever you are unsure about a command, type 'h' to get help on the available commands and their use cases.
• Keep It Simple: Start with smaller segments of code to debug. This helps simplify understanding how specific portions of your code are functioning.
• Log Your Findings: Keep notes about what you learn during debugging sessions. This helps in future debugging efforts and increases your coding skills.

    # Sample Perl Debugging Example
    my $number = 42; # Set a breakpoint here
    my $result = factorial($number);
    print "Factorial of $number is $result\n";
    
    sub factorial {
        my $n = shift;
        return 1 if $n == 0;
        return $n * factorial($n - 1); # Step into this function
    }
