And consider that this has been simplified, at one point four branches 
plus default were being supported at the same time.

Excellent.  The most frustrating part of CPython development from my 
viewpoint is the massive number of open issues on the bug tracker that 
have patches, but simply sit there for years doing nothing except gather 
dust.  Anything that can be done to improve this situation is IMHO long 
overdue and extremely welcome.
