In my new consulting position, I've had to take up coding again as part of my Testing Analyst role. I'm also pretty new to Perl. I'm finding I love the language, but I'm occasionally confused by the multiple ways there are to do most things.

What I am looking for is the easiest/best way to know how many keys there are in the nth dimension of a multidimensional hash. (ie $hash{x}{y}).

For example, I'm using a 2D hash where I have the key to the first dimension, but I want a count of the number of "records" that exist for the 2nd dimension. And then return the value of a specific "record".
