import std.stdio;
import std.variant;

struct S;

void main()
{
    S * p;
    auto v = Variant(p);
}

Error: struct deneme.S is forward referenced when looking for 'toHash'
Error: struct deneme.S is forward referenced when looking for 'toString'
Error: struct deneme.S unknown size
Error: struct deneme.S no size yet for forward reference
Error: struct deneme.S unknown size
Error: struct deneme.S no size yet for forward reference

Being a user of Variant, std.concurrency is affected when sending messages of pointers to opaque types.

Same issue perhaps?


struct MyStruct;

MyStruct*[] arrayOfPointers;

arrayOfPointers ~= null; // fail
arrayOfPointers = new MyStruct*[n]; // also fail

Complains:
Error: struct MyStruct is forward referenced when looking for 'toHash'
Error: struct MyStruct is forward referenced when looking for 'opCmp'
Error: struct MyStruct is forward referenced when looking for 'toString'
Error: struct MyStruct unknown size
Error: struct MyStruct no size yet for forward reference
Error: struct MyStruct unknown size
Error: struct MyStruct no size yet for forward reference
