Temtaime:
Why? Compiler doesn't know if a + b fits in uint, right?
Then why overflow with ints are accepted?
It's an inconstancy based on practical considerations.
Walter decided that applying the same rule to uint/int/long
causes too many casts in normal problems.
And the range of a 32 bit int is much larger than the range of a
ubyte/byte/ushort/short, so in normal programs the probability of
overflowing an int by mistake is much lower than overflowing a
ubyte.
So your example is meaningless.
You should be more gentle if you want people to keep giving you
answers :-)
