If you are working on features which you are hoping to get integrated into Moodle core then you should be aware of the Moodle coding style guidelines: http://docs.moodle.org/dev/Coding_style
Every once in a while a discussion comes up about coding style where its not clear or there are requests for clarification or changes to the style. At the moment these things tend to linger on the wiki talk page and its difficult for people to follow the discussion or make a decision.
In order to improve the situation we have created a Coding style component in the tracker under the MDLSITE project. If you wish to request a change or clarification about style, please file a bug there. We hope that that this can be a place where discussions can be had and interested parties can keep informed.
I should point out that any coding style is never going to please all developers and so whilst we will strive to please everyone it is likely that the final decision will usually rest with the integration team and/or lead developer. We will also try our best to avoid bike shed painting.
Of course we'd be happy to hear your views on this.
Dan & the rest of the integration team
