Tracing Execution,racing can reveal to you the inner workings of libraries and modules, by the use of customized stack traces, not only your code, but also code which your program uses and that you have never even seen, let alone written..The next chapter explores several specialized breakpoint commands for working w

Debugging Modules,ecution across multiple libraries at both compiletime and runtime..You can use these commands to stop a program, not just at the first executable line of your main program, but also before it has even been loaded completely. You can do this before a BEGIN block has been run, or inside a BEGIN block

Debugging Object-Oriented Perl,o you for each object. You’ve also learned how to inspect the call tree, via a stack trace on an expression, which allows you to see what will happen when an object is called with an apparently unrecognized method or argument..In the next chapter we’ll take a look at how you can use the Perl debugge

This frees us from the necessity of having to work on the same

Finally, you learned how to inspect your code for strange or nonoptimal programming constructs, using the frontend O and backend B modules, which provide access to th
