Sorry guys I've seen the issue. I was recursively checking 
structs `static if (is(mtype == struct))
` (did not put this in example), my code found Nullable (a 
struct) defined as
```
struct Nullable(T)
{
     private union DontCallDestructorT
     {
         import std.traits : hasIndirections;
         static if (hasIndirections!T)
             T payload;
         else
             T payload = void;
     }

     private DontCallDestructorT _value = DontCallDestructorT.init;

     ...
}
```
