I think is very bug-prone, isn't it obvious iub should be -5?

ubyte ub = 5;
int iub = -ub; // iub now is 251

What is the reasoning to do it this way?

Minus toggles the most significant bit, be it on a signed or unsigned type. When converting it to an int, the byte being signed or unsigned does make a difference: when unsigned the number is copied as is, when signed the most significant bit (bit 7) is shifted to the most significant bit of the int (bit 31).

Its therefore pretty standard logic, no warning is given since the entire ubyte range fits within an int
