I'm having trouble getting Perl 5.10 features working in the Perl debugger.

I'm using Perl 5.12.3 on Red Hat Enterprise Linux 6, starting the debugger with the following line:

perl -dE0

and I get the following error when I run say "Hey";

String found where operator expected at (eval 11)[/s/perl-5.12.3/amd64
+_rhel6/lib/5.12.3/perl5db.pl:638] line 2, near "say "Hey""

+^D = $^D | $DB::db_stop;

Doing use '5.12.0', or use feature ':5.12' doesn't help either. How can I get this to work?
