XL is an extensible programming language that allows programmers to easily adapt the language to their needs by adding new constructs. The language includes built-in operations commonly found in other programming languages, making it suitable for a wide range of tasks from simple scripts to complex compilers. XL aims to provide complete control over the programming process, with the capability to match the efficiency of languages like C or Ada in specific domains. The language features a single operator, “is,” that can define various entities, including variables, functions, operators, and more. XL’s standard library encompasses common programming features, ensuring consistency across implementations. The language’s extensibility and versatility make it a promising tool for developers. Note: The XL compiler is still under development and may not be suitable for serious programming tasks.
