List Comprehensions and Pattern Comprehensions

[x IN list WHERE pred | expr] and [(n)-[:R]->(m) | m.name] — Cypher's two functional power-tools.

Why it matters

Pattern comprehensions let you 'project a pattern' inline, no extra MATCH needed — perfect for shaping nested JSON.

Make it stick

Use the prompts below to anchor list comprehensions and pattern comprehensions to a real graph you own.

›Pick a graph workload you've shipped — where would *list comprehensions and pattern comprehensions* have changed the design?
›What's the smallest version of this pattern you could prototype on a real dataset next sprint?
›What is the most likely *misuse* of this idea, and how would you catch it in a model or query review?
