Thanks. Regarding:
https://dlang.org/changelog/2.099.0.html#allow_casting_from_typetuple_to_typetuple

I don't understand why this is allowed:

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

void foo()
{
     Tuple!(int, int) tup;

     auto foo = cast(long) tup;
     pragma(msg, typeof(foo)); // (int, int)
}
```
Casting 2 values to one type is weird, and why does it not affect 
the result type?
