Hello Gregory,

I have recently published experimental and low-level FFI bindings to 
atomic primitives including CAS as 'bits-extras' on Hackage [1].
Instances for Int and Word types are included.

This is likely lower-level than what you are after, but might still be 
handy for experimentation.

Kind regards
