Is it possible to avoid call to destructor for structs?

No, but you could just set a flag in Bar that the destructor 
checks and skips running if it is set.

In fact, the destructor should do nothing if bar is in its 
initial state, so that's how you could check it. For example

~this() {
    if(this.member is null) return;
    // finalize this.member
}
