NF FTW (Native Facts For The Win).
It might be nice to keep this project around for the pseudo-reflection "where's this symbol defined" api. If this is the direction the Meta team wants to pursue, the following steps would have to be taken.

- Make initialize() a noop.
The hack Oss world should update their bin/ scripts to stop looking for the autoloader.
