Yeah, but I think they were added in 5.10, and when possible I try to give examples using 5.8 features. (Something like say is excusable, because it's so easy to write a shim for it.
sub say { local $\ = "\n"; print(@_ or $_) }
sub IO::Handle::say { my $h = shift; local $\ = "\n"; $h->print(@_ or
+$_) }
I also quite like this way:
use constant {
IX_FILENAME => 0,
IX_RUN => 2,
IX_DISTRICT => 8,
IX_COPY => 9,
IX_TOTAL => 10,
};
print Dumper
map {
Dumper($_), $_->[IX_FILENAME]
}
sort {
$a->[IX_RUN] <=> $b->[IX_RUN] or
$a->[IX_DISTRICT] <=> $b->[IX_DISTRICT] or
$a->[IX_COPY] <=> $b->[IX_COPY] or
$a->[IX_TOTAL] <=> $b->[IX_TOTAL]
}
map {
[ $_, split /_/ ]
}
@files;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
