I suppose a more devious method to find the size of a hash

Why would you use a "devious method", when scalar keys %{ $hashref } gives you it directly, without 1) iterating the entire hash; 2) contructing an array to hold the keys and values of the hash; 3) throwing away all that work and memory having only extracted a count; which you then have to divide by 2 anyway?

In the absence of evidence, opinion is indistinguishable from prejudice.
