What mess? The actual fix for issue 259 is simple, elegant, and 
shouldn't require much code in the wild to be changed.

The difficulties and delays have all been associated with the 
necessary improvements to VRP and constant folding, which are 
worthwhile in their own right, since they help the compiler 
generate faster code.
