I wouldn't use that as a primary example (allowing integers to overflow), because one of the great things about Julia is that it is incredibly easy to define your own types that will simply work, that for example, do checked arithmetic on integers (SaferIntegers.jl, I think is one, or don't want a limit (BigInt, which is included in Julia). Julia gives the programmer the choice, and not only that, allows the programmer to create their own choices.
