As processor get more complex and languges develop more features, the debug tools
naturally get more complex to be able to show the maximum info.

One thing is if you use a class as a data member, you can examine the data member
class.
Also, if you have a pointer to a parent class, you can examine the parent.
You can also modify variables more easily.

I find GUIs are helpful but I can certainly live without them.
You haven't lived till you've debugged by useing a frontpanel that give you
hardware access in binary and you single step by pussing a switch or modify memory
locations directly from the panel.  It's also great fun to patch you code by
toggleing instructions in in binary.

Then there's having a logic analyser without an emulator pod and you hook up
probes to the address and data busses to decode what's going on.

If you want maximum debugging, you have to roll up your sleeves and dig.
