Zig also differentiates between the wrapping and non-wrapping operators. The for loop example would toss a runtime error when the index underflowed in most compiler modes.

The if statement won't work since Zig would force a cast.

The tricky wrap sucks unless you use a power of 2. Then the Zig type can match (u4, u5, u7, etc.) and you would use wrapping arithmetic operators. And on smaller CPUs you NEED to use a power of 2 because division and mod are expensive.
