Others suggested casting as a solution which works but it will hide
potential errors.
Depending on the

Not what you might expect if you are doing addition.
Quite similar to int.max + int.max
Indeed. But this is where

Because C didn't define it that way. And C didn't define it that

Oh btw, D's byte is signed, range -128 to 127, unlike C# where it
is unsigned.
C#'s `byte` is represented as D's `ubyte` (meaning "unsigned
byte"), range 0-255.

In fact, D promotes all integral types smaller than int to int

Well, it DOES have a + operator, it just returns int that can be
squished to a size if and only if the compiler proves it fits.
A bit of background: the C language was designed on
