Hi! Are you aware of the `-checkaction=context` compiler flag? 
Give it a shot:

```d
unittest {
     int x = 0, y = 5;
     assert(x == y);
}
```
```sh
dmd -main -unittest -checkaction=context -run ./example.d
```

```
onlineapp.d(3): [unittest] 0 != 5
1/1 modules FAILED unittests
```

Test on [run.dlang.io][0].

This is not an argument against a dedicated assertion module, but 
I think it's good to be aware what can be achieved at the 
compiler/runtime level vs library level.
