Package names. Sameer Ajmani 4 February 2015 Introduction. Go code is organized into packages. Within a package, code can refer to any identifier (name) defined within, while clients of the package may only reference the package's exported types, functions, constants, and variables. Then why give variables vague names like a, n1 etc. An example would be naming a collection of Person objects persons_list when it is not actually a List. This name could misguide other developers towards thinking that it is a List type object.
