Not only undocumented, but untested and they are actually look plain
wrong when looking at that diff. Notice how "reduction" is imported
using from .context import reduction and then changed inside the
"context" module using globals()['reduction'] = reduction. That
seems unlikely to produce any effect.
(not to mention the abstract base class that doesn't seem to define any abstract methods or properties)
To be frank such an unfinished patch should never have been committed. I may consider undoing it if I find some spare cycles.

Antoine.
