I use ``dmd package.d -verrors=3 -debug -I"../.."``.
I get
```sh
Error: undefined reference to
`std.container.array.Array!(minimal.token.token.Token).Array.empty() const`
referenced from `const bool
std.container.array.Array!(minimal.token.token.Token).Array.opEquals(ref const(std.container.array.Array!(minimal.token.token.Token).Array))`
```
