Hi D

As suggested in other threads I've tried wrapping a SumType in a structure to add functionality and used alias ... this to make assignment, etc. easier. However the following code fails in dmd 2.105.2.

import std.sumtype;

struct Item{
  SumType!(void*, byte[3],  ubyte[3], string[3]) value;
  alias value this;
  this(T)(T thing){ value = thing;}
}

void main(){
  Item item;
  byte[3] byte_vec = [0x01, 0x02, 0x03];
  item.value = byte_vec;   // <-- works
  item = byte_vec;         // <-- fails to compile
}

Is there some important detail I'm missing? The compiler error message is:

Error: generated function `test_sumtype3.Item.opAssign(Item p)` is not
       callable using argument types `(byte[3])`
       cannot pass argument `stuff` of type `byte[3]` to parameter
       `Item p`

Thanks for any suggestions,
