import std.stdio;
struct Struct
{
   this(int value) { writeln("Struct.this(", value, ")"); }
   ~this() { writeln("Struct.~this()"); }
}
void main()
{
   Struct s = Struct(1); // prints `Struct.this(1)`
   s(2);   // prints `Struct.this(2)`

s(3); // prints `Struct.this(3)`

} // prints `Struct.~this()`

Notice how the destructor is only called once. If there was an opCall defined for Struct, its reconstruction would shadow it. It certainly looks like a bug to me, but since I'm "sure of nothing" in D I decided to post it here. Is it really a bug?
