           Summary: Lack of read-modify-write operation check on shared

In git-head, issue 3672 is fixed, but its implementation is not enough.

Test case:

void main()
{
    shared int n;
    n++;    // deprecated RMW operation
    n *= 4; // deprecated RMW operation

    struct S { int var; }
    shared S s;
    s.var++;        // no deprecation
    s.var -= 2;     // no deprecation
}
