Noteworthy:

const AliasSeq!(int, int) b;
pragma(msg, typeof(b)); /* (const(int), const(int)) */

Not and ER, that is well a bug, according to https://dlang.org/spec/const3.html#const_type

> [...]. Each applies transitively to all subtypes.

The problem is that the DMD class `TypeTuple` (in mtype.d) does not override
`.constOf`, `immutableOf()`, etc.

Tagging as accept-invalid given that

```d
alias AliasSeq(T...) = T;

const(AliasSeq!(int, int)) a;

void main()
{
    a[0] = 1;
}
```

should be reject just like when `const` is variable storage class.
