static variables don't have the .offsetof property:

struct S {
    int a;
    static int b;
}


// Bonus question: should field be alias or string?
template isStaticVar(T, alias field)
{
    enum isStaticVar = !__traits(compiles, mixin("T." ~ field ~ 
".offsetof"));
}

void main() {
    static assert (!isStaticVar!(S, "a"));
    static assert (isStaticVar!(S, "b"));
}
