Using a variant can also be a good solution:

```d
alias T = ubyte;/*
           char;//*/
alias R = const char;

import std.stdio, std.variant;
void main()
{
     T u; R v;
     writefln("%d : %d", u.sizeof,
           (true ? u : v).sizeof); // 1 : 4

     ubyte x1 = 16;
     x1 *= x1; // equal x1 = cast(typeof(x1))(x1 * x1);

     typeid(x1).writeln(": ", x1); // ubyte: 0


     Variant x2 = 16;
     x2 = x2 * x2;

     typeid(x2).writeln(": ", x2); // 
std.variant.VariantN!32LU.VariantN: 256

}
```

Integer promotion is a known thing. There's nothing we can do 
about it. It is not a coincidence that he was chosen especially 
int. If you are going to work on very large numbers, use BigInt 
and 100% string.
