Welcome to the fifth post about the Kephra Base Object System, where I explain the need for three kinds of attributes: data, delegating and wrapping and gas a little about their properties. It is especially advised to have read the first part (scopes) and the previous part, since accessors are methods.
In case you wonder how practical this exercise is - I already implemented a slightly simpler version and currently rewrite it. It's a standalone bundle of modules with its own tests and docs named Base-Class (Kephra::Base::Class) (123kB), which depends only on the bundle Base (there are the data types) (32 kB). So once ready it could be released on CPAN without much work.
After scopes, types and signatures we got all the prerequisites to talk about the syntax and semantics of KBOS methods. Unless you want to contribute to Kephra or write a plugin, you may never use them, but please join me in the thought experiment - maybe we get a littler smarter.
After introducing KBOS I should write about the most fundamental concept in this Perl syntax extension. In fact it's so basic, you could use it even without objects.
Starting even before Moose, we (in the Perl 5 world) have a plethora of Modules extending the syntax of the language with Perl 6 and more in mind. The following article sums up not only my 2 and a half cents on the subject but also an attempt to implement it. It should be of interest to anybody thinking about programming in general.
The Chaos Communication Congress is the hugest convention and festival for hackers on the continent. Its part 5-9 track lecture conference, part massive parallel soldering and other workshops, part dance party and part carneval. I liked especially the one guy, just walking around while making music on it's novation circuit - but there was so much going on - he was hardly noticeable. Because it was gigantismic. When even a small self made booth for baking dough (one of several dozens food stands) sells over a ton (literally > 1000 kg), serving > 13000 people, it earned its name: waffle operation center (WAP). But that's the spirit and humor around here.
