Local alias to the magical line array, C<@{$main::{'_<'.$filename}}> ,
supplied by the Perl interpreter to the debugger. Contains the source.

=head1 DATA STRUCTURES MAINTAINED BY CORE

There are a number of special data structures provided to the debugger
+ by
the Perl interpreter.

The array C<@{$main::{'_<'.$filename}}> (aliased locally to C<@dbline>
via glob assignment) contains the text from C<$filename>, with each
element corresponding to a single line of C<$filename>.

Seems to be magic. Dunno if it depends on debug flags or just the context of the DB package like other magic (e.g. @DB::args )

Anyway, let us know if you'll find something details about that magic. ;-).
