> $is_prime &&= $n % $_ or last for 2 .. sqrt $n;
why so complicated, isn't a simple flag sufficient?
#!/usr/bin/perl
use warnings;
use strict;
use feature qw(say);
for my $n (2 .. 99) {
my $prime = 1;
for (2 .. $n-1) {
$prime = 0, last unless $n % $_;
}
say $n, ' is a primer number' if $prime;
}

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.
