perldebguts

Hello.

Rather than a typo or an error, I think I've found a way which
could make perldebguts clearer.

In paragraph "Debugger Internals" there's this phrase: 

  << Each array @{"_<$filename"} holds the lines of $filename 
     for a file compiled by Perl. >>

In paragraph "Writing your own debugger":

  << @DB::dbline is an alias for @{"::_<current_file"}, which 
     holds the lines of the currently-selected file (compiled 
     by Perl) [...] >>

Now, I think in the first sentence package qualifier should be
mentioned, so I propose:

  << Each array @{"::_<$filename"} holds the lines of $filename 
     for a file compiled by Perl. >>  

What do you think?

thank you
Stefano
