Which and why?
while (<>) { ... } or while (my $line = <>) { ... }?
-w or use warnings;?
sub CONSTANT () { ... } or use constant CONSTANT => ...;?
my ($foo, $bar) = @_; or my $foo = shift; my $bar = shift;?
for (@array) { ... } or foreach (@array) { ... }?
print 'foo'; or print('foo');?
'simple string' or "simple string"?
glob '*' or <*>?
readline *FOO or <FOO>?
for (keys %foo) { $_ and $foo{$_} } or while (my ($key, $value) = each %foo) { $key and $value }?

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).
