Uhm, IO::Handle is just a bunch of methods that allows one to write $handle->func(args) instead of func $handle, args, with func being a core function. Many of its methods are of the form:
sub core_function {
... Check number of arguments ...
core_function($_[0], $_[1], $_[2]);
}
The objects are blessed handles, not the most convenient things if you want to subclass and actually store attributes, unless you want to go the inside-out-object way or some other "late great OO framework".
IO::Handle actually abstracts little (it just gives some different syntax), and isn't the easiest to subclass. It doesn't really impress me.

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).
