Debuggers usually have problems debugging scripts that have their own
event loops (as any GUI application does) if they don't have explicit
support for it. BlackAdder goes to some trouble to co-operate with the
Qt event loop in the script being debugged (that's what the PreHook and
PostHook options are for - see qapplication.sip).

One thing that I really liked about Tk was the ability to execute Tcl
statements at the wish prompt while your script was running. BlackAdder
allows you to do the same thing.
