Alias games aside, I have yet to read any argument for why \N{NAME} should not simply use the currently active charmap, and/or autoload the :full one. This would handle all but the rarest sitatuations, and it would make Perl stop violating the principle of least surprise.
In other words, instead of generating an exception like Constant(\N{NAME}) unknown: (possibly a missing "use charnames ...")
It should in that situation implicitly do a
use charnames ":full";
and get on with it. In other words, if you need a charmap and don't have one, just load what everybody is expecting.

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).
