Quite amount of interest exists in use of Perl for interprocess message passing and object-oriented persistence, in fact there is a list called poop-scoop (perl 0bject-oriented persistence) devoted to this this topic.

Cons is a tool for constructing software systems --- a Perl-based make replacement.

However, as I was reading through its docs, I noticed that it automatically would export scalars from a Cons program (nothing but a perl script that uses the Cons API) in one directory to a Cons program in another... poof! This means it does message passing for you without learning POE or Class::Tom or some other beast.

So now I unveil my tour de force, my arc de triomphe, my yo-check-it-out-daddy-its-megafresh, example of having Cons automatically serialize my data (ala, Data::Dumper or Freezethaw or Storable) and de-serialize it in another process: 

# This is a Cons "Construct" file. It exports a scalar
# named po, which is received by the perl program
# tmp/Conscript
$po = { 1, 'two', 'buckle my', 'shoo' };

Export qw (po);
Build  qw (tmp/Conscript);

[download]
# This is the tmp/Conscript. I receive serialized data and
# process it, in this case, simply printing it to STDERR
Import qw( po ) ;

use Data::Dumper;
warn Data::Dumper->Dump([$po],['po']);

Output of run is


$po = {
        1 => 'two',
        'buckle my' => 'shoo'
      };
