well, my take is that it works for the same reason that values now
(5.6+) returns aliases to the actual values of a hash. people wanted
access the the actual values of a hash when doing
foreach ( values %hash )
so they can mung them. so just using %hash and getting a list of
key/value pairs would behave the same but obviously the keys have to be
copies or you would have to rehash if you modified them. the values are
aliased the same way as if you used values.
so
chop %hash ;
and
chop values %hash ;
do the exact same results with different levels of efficiency and golf
scores. typical of abigail to notice that. :)
