There is a wishlists, blueprints, design and implementation notes document
that I posted over a year ago which is far more detailed than any launchpad
blueprint I have seen as part of this project.  You can still get a copy of

Because where inlined in the header file, they should generate identical
code.  Otherwise you cannot tell what was broken.  BTW, I have done this
once already, so I speak from experience and am not predicting a result.
