Unfortunately we have some servers with perl 5.6 and 5.8 on them. I want my script to be able to still run with the older versions, but if it is running something newer I want it to use an efficient module.
So basically I want to do something like:
if ($] > 5.010) {
use Super::Cool::Module;
$supercool = 2;
} elsif (($] <= 5.010) && ($] > 5.008)) {
use Almost::Cool::Module;
$supercool = 1;
} elsif ($] <= 5.008) {
print "No module available for this ancient perl\n";
$supercool = 0;
## insert code here to duplicate the functionality of the newer module
+s.
}
### then later in the code
if ($supercool == 2) {
# do stuff with the super cool functions
} elsif ($supercool == 1)
# do stuff with the less cool functions
} else {
# 10000 lines of code to implement the super cool functions in ancient
+ perl.
}
Is this really the best way to go? Just doing this psudocode here looks really messy to maintain.

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).
