Long time ago, I took a pascal course and there was a tracing program where I can actually step through the program and I personally think perl's debugging mechanism is little bit behind.
While it's not state-of-the-art, Perl's debugger is useful either by itself or when used from another tool.

The full version of Komodo IDE comes with Perl debugger integration, allowing you to visually set/clear breakpoints and to step through the code as with other IDEs.

The Data Display Debugger also integrates with the Perl debugger in a way familiar to users of GDB, allowing you to trace the execution of your programs and to visualise the contents of your data-structures over time.

Aside from "backward in time" debuggers which are starting to appear recently, the state-of-the-art is probably Visual Studio 2005's .NET debugger. Specifically the edit-and-continue and exception tracing facilities are fantastic. Hopefully Perl will one day attract such tools.
