Your wish is granted (in 5.8.5):

$ perl -de0

Loading DB routines from perl5db.pl version 1.28
Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

main::(-e:1):   0
  DB<1> h rerun
rerun           Rerun session to current position.
rerun n         Rerun session to numbered command.
rerun -n        Rerun session to number'th-to-last command.

rerun reloads the program and applies all commands you've executed in the debugger to (theoretically) get you back to the same point.

That's very nice, and has many uses, but isn't what I was wishing for. That's a replay of the complete flow. I want the option to goto an arbitrary line in the code of a running process. Sure, it's not obvious what that means when there are e.g. closures in effect, but I guess that's something to figure out.	[reply]
