Hi,

Quoting from perldata:

"If you evaluate a hash in scalar context, it returns false if the
hash is empty. If there are any key/value pairs, it returns true; more
precisely, the value returned is a string consisting of the number of
used buckets and the number of allocated buckets, separated by a
slash."

Regards,
Alan Haggai Alavi.
