          Issue ID: 22156
           Summary: Can't use all-types slice of not-all-types AliasSeq as
                    type
           Product: D

            Status: NEW

```d
import std;
AliasSeq!(int, 0)[0..1] a;
```

This should compile, but it does not:
```
app.d(2): Error: `AliasSeq!(int, 0)` is used as a type
app.d(2): Error: can only slice tuple types, not `_error_`
```
