          Issue ID: 20123
           Summary: Impossible to disable post-increment/decrement
                    semantics
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

D implements post-increment/decrement with a lowered expression.
According to the docs; (auto t = val, ++val, t)

I'm implementing C++'s atomic<T> type, which implements `operator++` &
`operator--`, but I realised that the lowering is not atomic, and I seem to
have no way to implement the post-inc/dec operators explicitly such that I can
make them atomic.

To properly implement this library, I need a way to implement the post-int/dec
operators explicitly.
