My point is that learning to use something by implementing
it yourself only works in a limited amount of cases. Only if
reimplementation takes about the same effort as learning it
in another way, it's efficient enough to do. So, it works for
simple, small things, like most of the CPAN modules. But it's
rather inefficient for things like Tk, perl, relational databases, operating systems, driving a car, learning a language or operating
a television. And sometimes, it's even impossible. Surgeons
don't learn their trade by reinventing the human heart.
I'd say that when it's efficient to learn something by implementing it yourself is relatively rare.

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).
