I think your 'R' usage is quite handy. Here's another approach that can sometimes be useful: 

 % echo 'sub afterinit { $DB::single = 1 }' >> .perldb

That changes the Perl debugger's default to instead stop before running anything. See: 

 % cat .perldb
sub afterinit { $DB::single = 1 }

 % cat debugMod.pl
use LWP::UserAgent;
warn "Done";

 % perl -d debugMod.pl

Loading DB routines from perl5db.pl version 1.33
...

main::CODE(0x43050c)(debugMod.pl:1):
1:      use LWP::UserAgent;

  DB<1> s
LWP::UserAgent::CODE(0x26c274c)(.../lib/LWP/UserAgent.pm:3):
3:      use strict;

  DB<1> T
$ = LWP::UserAgent::BEGIN() called from file `.../lib/LWP/UserAgent.pm
+' line 3
$ = eval {...} called from file `.../lib/LWP/UserAgent.pm' line 3
$ = require 'LWP/UserAgent.pm' called from file `debugMod.pl' line 1
$ = main::BEGIN() called from ...
$ = eval {...} called from ...

  DB<1>

Skipping over the loading of modules can be a pain, so I wouldn't recommend leaving this particular .perldb in place most of the time.

(FYI, I couldn't get this to work under Windows w/o first fixing some bugs in perl5db.pl or else I'd show how the file has to be named perldb.ini and other required differences there.)
