In case it wasn't clear: I don't mean to suggest that no-debugger is superior to debugger.

WRT the benefits of interactive debuggers, I definitely see the advantages of faster debug cycles. Luckily, it's not often that I need to worry about the 'often missing for the bug' / 'callstack and threading info when an address is written to' style of bug by virtue of working in codebases with strong coding standards and diligent code review. Most of the bugs I need to fix are 'developer didn't think of scenario S when writing feature F' or 'developer has forgotten edge-case E', rather than 'code is broken e.g. address re-use'.

And as I said in a cousin comment, I can't deploy a system with trace. That 10 minutes is just spent building :-p
