Re: Hash Printing reveals Hash Memory Location

[tobyink]

You have:

 my %words = {};

You want:

 my %words = ();

Or better yet:

 my %words;

Essentially in that first line, you're adding an entry to the hash where the key is a reference to an anonymous second hash, and the value is undefined. Because you can't use references as hash keys, the reference is stringified (which looks like a memory location).

In other words, my %words = {}; is basically a shorthand for:

 my %words;
 my $ref_to_anon_hash = {};
 $words{ $ref_to_anon_hash } = undef;

Ah. Thank you!
