The core spec of Clyx is mostly stable but the standard library is still a work-in-progress.

The most recent Clyx version is **0.3.2**. The version is bumped every time the language core words (aka primitives), the standard library or the REPL get updated. The primitive set is expected to be indefinitely frozen once the version number reaches 1.0.

Clyx is a concatenative, stack-oriented programming language designed for simplicity, minimalism, and metaprogramming capabilities. It uses postfix notation (aka Reverse Polish Notation, RPN), where operations are performed on a global stack. Clyx features homoiconicity: code is structured as Q-forms (special forms to represent data similar to Python or Tcl lists), which can be manipulated as data and executed dynamically.

The Clyx runtime itself allows the programmer to redefine any already defined word, including the core ones and the ones from the standard library. Unlike e.g. Forth, where words are resolved at compile-time, Clyx words are resolved at runtime, so such redefinitions may affect all previously established behavior. That's why, as a rule, any **predefined** Clyx word, both in the language core and the standard library, must not exceed 6 characters. This is done to encourage programmers to define their own human-readable words (7+ characters long) without any risk of overwriting existing word definitions.
