Programming language Chora: Data types

Each data member definition (e.g. property or local variable) requires precise information regarding the content it is intended to store at the runtime. With this information, the Chora compiler can determine the right operations to perform on the member when it is initialized or involved as operand within an expressions.

Chora provides a rich set of built-in data types you can additionally extend by your own class, enumeration and set definitions. Following is the overview of the Chora data type system:
