hi, all monks:

I am learning POE, and I am confused about POE::Session's parameter HEAP.

I notice that POE::Session use its parameter HEAP like a hash, but I think HEAP should be a reference, and it is documented: " Heaps are by default anonymous hash references":

The example from its document: 
 sub _start_handler {
    $_[HEAP]{ts_start} = time();
  }

[download]
why does it use 
$_[HEAP]{ts_start} = time();

[download]
rather than 
$_[HEAP]->{ts_start} = time();

[download]

I think the $_[HEAP] should be a reference, it can't not be use like $_[HEAP]{ts_start}, but in POE::Session, it did use like this way and it did work well.

Can anyone give a tip?
