Figure 2: Cognitive Load Comparison
A. Traditional Approach (Reverse Thinking)
Developer Thought Process:
┌─────────────────────────────────────────────────────────┐
│ 1. "I need to declare method signature first" │
│ ↓ (Premature commitment) │
│ 2. "What exceptions might it throw?" │
│ ↓ (Speculative planning) │
│ 3. "How should I handle each exception?" │
│ ↓ (Nested structure planning) │
│ 4. "Now I can write the actual logic" │
│ ↓ (Finally: the core purpose) │
│ 5. "Wait, I need to add finally cleanup" │
│ ↓ (Additional complexity) │
│ 6. "Does this handle all cases correctly?" │
└─────────────────────────────────────────────────────────┘
Cognitive Overhead: HIGH
Planning Upfront: REQUIRED
Flexibility: LOW
B. Nyash Postfix Approach (Natural Thinking)
Developer Thought Process:
┌─────────────────────────────────────────────────────────┐
│ 1. "What do I want to achieve?" │
│ ↓ (Direct focus on purpose) │
│ 2. "Write the core logic" │
│ ↓ (Implementation first) │
│ 3. "If something goes wrong, what should happen?" │
│ ↓ (Natural error consideration) │
│ 4. "What cleanup is always needed?" │
│ ↓ (Resource management) │
│ 5. "Done! The signature is inferred." │
└─────────────────────────────────────────────────────────┘
Cognitive Overhead: LOW
Planning Upfront: MINIMAL
