use Perl

The debugger is loaded and started in a process that wasn't compiled with -d. Neat, eh?

for ( 1 .. 100 ) {
    if ( $_ == 50 ) {
        eval 'use Enbugger'
    }
}

Or maybe you'd like to do something about your exceptions a bit more manually...

if ( my $e = $@ ) {
    require Enbugger;
    $DB::single = 2;
}

If you weren't aware, the debugger has remote-debugger support. The following starts debugging and opens a console to whatever is listening on port 7000.

local $ENV{PERLDB_OPTS} = 'RemotePort=localhost:7000';
require Enbugger;
$DB::single 2;
