I hate D's policy on integer conversions.
The funny fact is: during CTFE this promotion to int is NOT
done.

Can we make `i < 256` a compile-time error?
This works, because i is promoted to int so it can an will
reach 256.
But during CTFE this is an infinite loop, because an ubyte is
always <256
One of the bugs that caught me on surprise.
It's an infinite loop at runtime. `i == 256` never happens, it
can't.
```d
void main()
{
import std.stdio;
for(ubyte i = 0; i<256; ++i)
i.writeln;
}
```
