- Move most of the built-in functions to libraries that are in the core. So, instead of log(), it would be Math::log() and use Math; would bring those functions in. This goes for about 70% of the functions. This makes the whole CORE:: and CORE::GLOBAL:: thing a bit easier to manage.
- Get rid of prototypes and find a real way to pass an array as an array to a function. The only suggestion I have is calling signatures.
- @ISA is a hack, as is UNIVERSAL::. All OO should be left for a module. The only good thing is bless().
And, the biggest thing is the variable tying system. I love variable tying. But, it should be really be implemented through some form of autoboxing vs. the rather ad-hoc-ish mechanism that is TIE. Having dealt with nearly every intricacy you can with DBM::Deep, there are certain parts I just go "Uhh ... it passes all the tests!" and leave it at that. At the very least, there needs to be a massive amount more documentation of exactly what gets called in what scenarios. But, autoboxing would solve the issue nicely.
Of course, we can't autobox without a solid OO system. I'd just like to autobox with Moose. But, I can't without a performance penalty that's ridiculous above what tie imposes. So, I don't.
My criteria for good software:
- Does it work?
- Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
-

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).

or How to display code and escape characters
are good places to start.
