Option/result [[Type_system|types]] are used, where the option type ({{code|?}}) can be represented by {{code|none}} (among possible choices) and the result type ({{code|!}}) can handle any returned errors. To ensure greater safety, the checking of errors are mandatory in V. By default, among the following are [[immutable]]: variables, structs, and function arguments. This includes string values are immutable, so elements can not be mutated. Other protections, which are the default for the language, are: no usage of [[undefined value|undefined values]], no [[variable shadowing|shadowing of variables]], no usage of [[null pointer|null]] (unless code marked as unsafe), and no usage of [[global variable|global variables]] (unless enabled via flag).
