Note B::Deparse can be a useful tool:
$ perl -MO=Deparse -we 'use strict; my $value=1; my $lower_limit = 0;
my $upper_limit = 2; if ( ( $value <= $upper_limit )
&& ( $value => $lower_limit ) )
{ print "the value is in the range!\n"}'
Useless use of private variable in void context at -e line 4.
BEGIN { $^W = 1; }
use strict;
my $value = 1;
my $lower_limit = 0;
my $upper_limit = 2;
if ($value <= $upper_limit and $value, $lower_limit) {
print "the value is in the range!\n";
}
-e syntax OK
Say perl -MO=Deparse,-p ... to add parentheses and see the precedence better.

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).
