Overloading Diagnostics (Programming Perl)

13.10. Overloading Diagnostics

If your Perl was compiled with -DDEBUGGING, you can view diagnostic messages for overloading when you run a program with the -Do switch or its equivalent. You can also deduce which operations are overloaded using the m command of Perl's built-in debugger.

If you're feeling overloaded now, maybe the next chapter will tie things back together for you.
