This is the proposal (first paragraph of the DIP / Abstract): 
"Reads and writes to data typed as shared are made atomic where 
the target CPU supports atomic operations and become erroneous 
when they cannot be done atomically."

The rest of the DIP sometimes seems to contradict the Abstract 
(e.g. "prohibiting direct access to shared data", "will require 
using core.atomic"). It should probably be clarified that using 
core.atomic will only be necessary when the compiler can't 
generate the atomic operation itself for whatever reason.
