Okay... attached you will find POE::Session::SubVar (for lack of a better name). There's a script called demo.pl which should be self-explanatory. And from the scanty documentation, it'll allow you to do things like:
use POE::Kernel;
use POE::Session::SubVar;
POE::Session::SubVar->create(
inline_states => {
_start => sub {
warn "\@_: @_";
kernel->yield('count' => 1);
},
count => sub {
my ($count) = @_;
print "counted to $count\n";
kernel->yield(count => ++$count) if $count < 10;
},
_stop => sub { warn "done" },
},
args => [qw(foo bar baz)],
);
$poe_kernel->run();
exit 0;
and
POE::Session->new(
inline_state => sub {
my (@args) = @_;
heap->{args} = \@args;
kernel->yield('object_state');
},
$object => ['object_state'],
);
sub object_state {
my ($self, @args) = @_;
...
}
Rocco, perhaps if you're agreeable, you could put it (or something similar to it) out at http://poe.perl.org/poedown and update the info at http://poe.perl.org/?POE_RFCs/Lexical_state_parameters to point to it?
