1. You have the type for dynamic arrays, called TypeRcArray, 
syntax is  `Type[+]`
2. You have the type for slices (what you describe as a 
window), syntax is `Type[]`
but it is mostly obtained using expressions, e.g `mySlice = 
myRcArray[lo .. hi]` or
`myStaticArray[lo .. hi]` or `myPointer[lo .. hi]`.

This sounded like a good idea but it [has appeared very 
quickly](https://styx-lang.gitlab.io/styx/type.html#noteonlifetime) that slices are not so useful...

Recently DIP1044 was published about enum and although we can use 
`with()` instead we waste time unnecessarily...

I've never tried it, but the feature shown below is not available 
in D! Why not such good things?

```d
enum Foo
{
     a0 = 1,
     a1
}

enum Bar: Foo
{
    a2 // 3
}
```

Thanks...
