-# GT – Boolean Operators (RPN Only) Implementation Plan
-
-## Overview
-The **gt** project currently evaluates arithmetic and percentage expressions via a REPL that supports RPN (postfix) syntax.  To make the language more expressive we will add a full set of Boolean comparison operators, but **only** in the existing RPN form.  No infix parsing will be introduced.
-
-## Goals
-- Provide the six common comparison operators as postfix tokens:
-  - `gt`  → `>`  (greater than)
-  - `lt`  → `<`  (less than)
-  - `gte` → `>=` (greater‑than‑or‑equal)
-  - `lte` → `<=` (less‑than‑or‑equal)
-  - `eq`  → `==` (equal)
-  - `neq` → `!=` (not equal)
-- Extend the RPN stack to store boolean values alongside numbers.
-- Ensure the new operators work with all numeric types supported by the existing calculator (int, float, unsigned) and handle edge cases (NaN, Inf, division‑by‑zero). 
-- Add thorough unit tests and update documentation.
-- Integrate the changes into the CI pipeline and bump the project version.

-## Plan:
-1. Extend the REPL value system to support a boolean type for RPN stack values.
-2. Implement the postfix operator `gt` (greater‑than) as an RPN operator.
-3. Implement the postfix operator `lt` (less‑than) as an RPN operator.
-4. Implement the postfix operator `gte` (greater‑than‑or‑equal) as an RPN operator.
-5. Implement the postfix operator `lte` (less‑than‑or‑equal) as an RPN operator.
-6. Implement the postfix operator `eq` (equal) as an RPN operator.
-7. Implement the postfix operator `neq` (not‑equal) as an RPN operator.
-8. Register all new operators in the RPN operator registry.
-9. Update the existing `RPNHandler` to recognize and dispatch the new operator symbols.
-10. Add unit tests for each new operator covering numeric types, mixed‑type comparisons, and edge cases (NaN, Inf, zero divisor).
-11. Update godoc comments for each operator and extend `README.md` with a table of Boolean operators and RPN usage examples.
-12. Modify the CI pipeline to run the new tests, bump the module version to the next minor (e.g., `v0.2.0`), and add a changelog entry documenting the new Boolean operators.
