I would recommend the other answers over my own.
my $cnt = scalar keys %hash;
seems more readable to me.

This goes right along with my problem. How can you tell how much memory
(RAM) the hash takes?

No, it means 3 out of the 8 buckets allocated have been used. This
doesn't tell you the number of keys, unless (by some terrible
misfortune) all your keys have found their way into unique buckets

You can print the hash in

Nope, not quite. It returns the index of the last element. Putting your
list in a scalar context is a better way:
my $array_cnt = @array
This is what foreach does when

Dunno if you can avoid counting them, but $keycount = keys(%hash) will
do what you want. Hopefully there's an optimization somew
In an array to find the number of elements in an array I :
print "$#array\n";
Is there a similar way to find the number of keys in a hash without cycling
through them and without assigning the hash to an array?
