The nice thing about a one byte integer is that it's at the very bottom
of the food chain. Since casting upwards is implicit and downwards is
explicit, NOTHING casts implicitly to it. As such I'm hoping (like I
said in my original post - I'm no expert) that this will be a harmless
addition.
If there is anything you can think of that will allow me to verify this
claim, do let me know.
