That "package=TYPE(0xaddress)" is how perl stringifies an object
reference. The objects in @kiddies are SCALAR references blessed
into package "threads".
Plain scalar reference:
% perl -le 'print \2'
SCALAR(0x81aa374)
Blessed scalar reference (object):
% perl -le 'print bless \($x = 2), "threads"'
threads=SCALAR(0x81aa3bc)
