Suppose % if you gave a numeric argument to 't' it would trace up to that depth % in subroutine calls beneath the current level but not beneath? That % might be doable (as a patch to the debugger). Hmmm... That's a pretty attractive idea, actually. The point of -x, which certainly isn't much for one used to a debugger, is simply to print out each command that goes on and, as a bonus, see the values the script has at the time, and it's expected that you just dump that (stderr) off to a file and peruse it at leisure. The problem I've always had with a debugger is that you have to set breakpoints or step through EVERY SINGLE BLASTED STEP in order to see what's going on, and you want to not descend too far down into functions and such, and you still have to print values when you want to see how they're set at the time. I realize that the debugger is enormously powerful, and I'll lay a Twinkie on the line betting that with just a little experience the breakpoint thing gets to be downright easy and it's second nature to print something when you want to see it -- but dammit, Jim, I'm a novice, not a Perl monger! ... % > [ $var = true ] % > % >in your script). % % Not really feasible for anything except simple scalars... that's good % enough for the shell, but Perl goes much further.
