I can't forget to mention a Larry Wall frase:

"Do not try to discourage people from trying variances. We do not want to stabelish one church, we want to stabelish many denominations..."

We can't forget that reinvent the wheels is important to create a variance of codes, to create options, like in a genetic enverioment. And us, the users, will make the selection of what will live.

For example, when I started to work with XML and Perl, I can't find any tool that work like I want, since I always want tools that are easy, direct and powerfull. Soo, Perl in the time already have a lot of XML handlers, but I started to do my own, with a different approach to work with XML. Today XML::Smart works exactly as I want, and has much more than I can imagine when I start to build it, since the community always make good contributions. Soo, XML::Smart today is a tool that enable any Perl user to use XML, even if it don't know much about XML. Also I have got good reviews of it, including from IBM, that is the main creator of XML by the way.

Soo, if I can't find a tool with the resources that I want and the architecture that I need, yes, I will build my own. But before start building another CPAN module I always take a look around, including the source of what I find to see if they are in the right architecture, than I decide, to use it, contribute to it, or start a new module.

Soo, I have reinvented some wheels:

• Mail::SendEasy

Created it because I can't find a Mail sender based in SMTP (platform independent), that don't need big dependencies like libnet, that has authentication, and is able to send TXT & HTML messages, attachments, etc... All in one package.
• Pod-HtmlEasy

Well, after wait/search 1 year for a Pod 2 HTMl tool that handles index, css, and enable personalizable outputs, I stop to wait and build one. Soo, now I can have nice and well HTML builds on the flight, where I also can set my own events, and handle links (L<>), codes (VERBATIN), and all the POD syntax without care about the HTML generation, entities, URI links, etc...
• Class-HPLOO

This actually wasn't a new wheel, since I really can't find something that do that. I found Perl6::Classes, but it doesn't work very well, since is very easy to break the filter with complex Perl codes. But this is a bug of Filter::Simple and Text::Balanced, where I also make some work around to fix them on Class::HPLOO. But Perl6::Classes also have a complexer syntax, it isn't simplier as I want/need, since Class::HPLOO was designed to make the OO development faster and similar to Java, since my team work a lot with Perl & Java at the same time, and I was tired to listen the Java folks to disturb me about the Perl syntax for OO.

Soo, now I have Class::HPLOO that make the development of new modules and classes for development of systems much more faster and easy. Also I can have Perl developers that are not soo experts on PerlOO working with 100% OO codes. And the Java folks are using much more Perl now, actually they think to build in Perl before to think in Java solutions.

• XML::Smart

Let's mention Larry Wall again:

"I fill computer programmer not as something it has to do as computers, it has to do as humans. It's like, ok, I will going to make this easy to the computers or for ther person envolved?".

Soo, I think that XML need do be easy and simple to use and generate, since if it's not simple and direct, it won't make it job: "Be a language that integrate easy different applications and architetures.". Before XML::Smart I was really thinking that is much more easy to create our own formats, now XML rox.

Soo, if I think that I can make something better, yes I will, since no one is oblicated to use it, only to love it! ;-P
