That line of code is read pretty much the way it looks. It's like saying "Ok
Perl, I want you to grab all the values in this hash and glue 'em together
with a pipe character". So for example, a statement like that would be
assigned to a scalar as a string and you would do something with it. Your
string in this case would look like "value|value|value|..." Values is a
built-in function. If you wanted to iterate through the values of a hash you
would say something like
for (values %hash) {
There is a similar built-in called keys. You can guess what that does.
