Refactor MediaWiki Core into well encapsulated components, removing global state and circular dependencies between classes	Incrementallly refactor MediaWiki code into logical classes/components/libraries to isolate functions such as storage, parser, events and app logic. Prioritizing refactoring of code into components to allow: Easier testing (leading to faster development), more easily support both LAMP stack and WMF use cases that require scale and selective SOA, increased re-usability, enabling an API-first approach be de-coupeling the presentation layer. Removing global state also enabled full cross-wiki capability (e.g. loading and rendering content from multiple wikis in a single request).
