What are some good Perl debugging methods?

Question

Are there other ways for debugging Perl programs apart from Data::Dumper and perl -d?

Answer 1

My usual range of tools is:

• print statements and Data::Dumper for simple cases
• perl -d

That's usually enough. There is ffffd; I heard it's quite nice, but never played with it.

For some tasks (which are not really debugging, but close to it) I use Devel::NYTProf.
