Declared Constants

Several different language constructions are referred to as 'constants'. There are numeric constants (also called numerals) like 17, and string constants (also called character strings or string literals) like 'Hello world!'. Every enumerated type defines constants that represent the values of that type. There are predefined constants like True, False, and nil. Finally, there are constants that, like variables, are created individually by declaration.

Declared constants are either true constants or typed constants. These two kinds of constant are superficially similar, but they are governed by different rules and used for different purposes.
