This means nothing to the end user and huge change need to be made to +make it functional exactly the same as is right now, the main difference is +that, instead of relying on Clang type system, we have our own. + +For now it has the Clang type system disabled and detects D as usual, but does +nothing, when requesting any type information. + +The current changes for the implementation of D TypeSystem will be in +[this]( PR. + +I decided to create a seperate repository for this until I have a decent plugin +to upstream.
