OK changing it to (caller 3) made it work for me! =)

  DB<100>  w $main::{"_<".(caller 3)[1]}[(caller 3)[2]] =~ /\bprint\b/
  DB<101> r
0
1
Watchpoint 0:    $main::{"_<".(caller 3)[1]}[(caller 3)[2]] =~ /\bprin
+t\b/ changed:
    old value:    ''
    new value:    '1'
main::(tst.pl:13):    print $x++;

my suggestion is to define a new debugger command for "global-break-line" via an alias like bl in your '.perldb'.

Like that  bl REGEX is translated to w @{ [ DB::breakline(regex) ] }

sub DB::breakline { } is also defined in '.perldb' and handles the details to access the line's source and to return a new value.

tomorrow more!
