Is it possible to invoke the perl debugger at runtime? I'm currently working on Devel::Trace, writing a test suite for all the nifty changes.

But 'make test' runs - of course - perl without the -d switch. Stating use Devel::Trace @args doesn't initialize the debugger. My workaround is... 

use strict;
use Test::More tests => 1;
my $result = join '', `perl -It -Iblib/lib -d:Trace t/foo.pl 2>&1`;
my $expected = join '',<DATA>;
is($result,$expected);
__DATA__
* expected output here *

but that is inelegant as feck.

Does anybody of you monks know how to instantiate the debugger at or after compile time? Is it even possible?

Or, as another possibility, shoehorn the -d flag into the test suite?

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
