--============================================================
-- Strings Integrity Test Suite
-- Target: NumbersToExpressions Step
-- Author: SpinnySpiwal
-- Purpose: Prevent any further quality regressions from NumbersToExpressions.
-- There was no actual bugs per se, but the bug was the use of Vanilla Lua instead of LuaJIT.
-- This test ensures that the obfuscator stays client-agnostic & doesn't require a specific Lua version.
