 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.

+This document describes the stack effects and behavior of the **50 primitive core words**, **3 bootstrapped core words**, and **48 standard library words** present in the reference implementation.
 
 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.

+- **Stack Effect**: `( -- )`
+- **Description**: A no-op word (does nothing). Useful for syntactic readability in control flow.

+- **Stack Effect**: `( -- )` (parses actions Q-form from the execution stream).
+- **Description**: Defines the entry point of the program by setting the `_main` word to execute `[actions]`.
