I was looking over the PPI set of modules and am wondering if anyone uses it in the format: 
         # Create a document from source
         $Document = PPI::Document->new(\'print "Hello World!\n"');

I've tried several variations using vars, double and single quotes, but have been unable to get it to parse anything from memory. It *does* work if I give it a file, but the example above doesn't seems to work -- which seems pretty basic.

I'm wanting to use it for memory-based input and no files are involved, For example, I might want to parse the same line 2 different ways (maybe with a trailing semicolon, or w/o, or some other way).

I'm wondering what syntax is suppose to work -- I also pointed out that the documented example doesn't work in their issue database, but no response on that. So does anyone have any working examples? My basic framework (in a file called ppi_dump) looks like: 

#!/usr/bin/perl
use warnings;
use strict;

# use utf8; use open IN=>q(:utf8); use open OUT=>q(:utf8);
use PPI;
use PPI::Dumper;
use P;

P "parse: %s", $ARGV[0];
my $doc=PPI::Document->new($ARGV[0]);
my $dumpr=PPI::Dumper->new($doc, qw(whitespace 0 comments 0));
# .my $toks = $dumpr->list;   # for indirect access...
$dumpr->print;

A working example should suffice to jumpstart this -- from the documentation, I would have thought a string would have worked for my "arg", like: 

> ppi_dump 'print "Hello World!\n"'

parse: print "Hello World!\n"
Can't call method "list" on an undefined value at ./ppi_dump line 14.

FWIW, if I give it a filename, it shows the content of the file, parsed, but the parse from string is the issue.

Tnx...
