The following code works with dmd 2.098.1 but does not work with dmd 2.099.0 (beta).
```d
import std.sumtype : SumType;
struct None{}
class C1
{
SumType!(C1, C2) field;
}
class C2
{
SumType!(None, SumType!(C1, C2)[]) field;
}
void main() {}
```
dmd 2.099.0 shows the following message:
```console
> rdmd playground.d
Error: unknown, please file report on issues.dlang.org
onlineapp.d(7): Error: template instance `std.sumtype.SumType!(C1, C2)` error instantiating
```
