Nononon.. you missed the point. If I have a program that uses class Foo, and in my program somewhere else, i declare sub new, doing new Foo will break. It's not "why is the constructor called new" but if you do "new Foo" and new() exists on the same scope of your program.
Take this for example:
use Foo;
sub new(*)
{
die "wuh?";
}
$x = new Foo();
With a package..
package Foo;
sub new
{
return bless { a => 1 }, shift;
}
sub new2
{
return bless { a => 1 }, shift;
}
1;
new2 works, new breaks. THAT is my point. Why would anyone do this, I don't know. But people have pointed out that ->new is the better convention.
So before you berate me more on what a constructor is, i suggest you reread my posts. Thank you.
Play that funky music white boy..

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).
