The docs for Exporter (https://metacpan.org/pod/Exporter) include several
examples using global variables. These should be declared with 'our' where
appropriate to make the examples strict-safe. Right now this detail is
hidden under the "Good Practices" section but it should be applied to each
example the user sees directly -- remember that newbies are likely to stop
reading once they have copy-pasted something that "works".
