  $DB::single = 1; could be inserted into the module code for Some::Module::... to stop it at the right point.

  I've done the lazy version of a script, copy-and-paste 20 lines of debugger commands at a time to re-run them. It's inelegant, but like you, I took a look at the debugger code and averted my eyes :) However, I just took a glance at perldebug, and it says:

         You can mock TTY input to debugger by adding arbitrary commands to
         @DB::typeahead. For example, your .perldb file might contain:
  
             sub afterinit { push @DB::typeahead, "b 4", "b 6"; }
  
         Which would attempt to set breakpoints on lines 4 and 6 immediately
         after debugger initilization. Note that @DB::typeahead is not a sup-
         ported interface and is subject to change in future releases.

  I'm curious how well that works.

    in 2003, mjd worked on the debugger under a perl foundation grant, which was to include a deliverable of a refactored debugger.
    
    http://www.perlfoundation.org/gc/grants/2003_q4.html
    
    That would be very, very, cool if the code were available for hacking on... I haven't been able to find it, in quick google searches; I suppose I should email mjd. :)
