Deprecation: Read-modify-write operations are not allowed for shared variables

[Timothee Cour via Digitalmars-d-learn]

dmd 2.066(rc) generates warning: 'Deprecation: Read-modify-write operations
are not allowed for shared variables. Use core.atomic.atomicOp!"-="(a, 1)
instead.' for following code:

synchronized {
  ++a;
}

Is that correct given that it's inside synchronized?
