//! Consciousness-Inspired Computing Module
//!
//! This module implements artificial consciousness concepts for enhanced
//! query optimization and data processing, including:

#![allow(dead_code)]
//!
//! - Intuitive query planning using pattern memory and gut feelings
//! - Creative optimization strategies inspired by human creativity
//! - Emotional context for data relations and processing
//! - Dream-state graph processing for memory consolidation
//! - Quantum-inspired consciousness states for enhanced processing
//! - Emotional learning networks for empathetic decision-making
//! - Advanced dream processing for pattern discovery and insight generation
//!
//! These features represent the cutting edge of consciousness-inspired
//! computing in the semantic web domain.
