This looks solid, the type safety and automatic escaping alone would've saved me hours debugging Cypher strings. The batching is smart too. Curious how it handles variable-length paths though, since that's where most ORMs get messy. The AI agent memory use case makes a lot of sense.

Great question — variable-length paths are fully supported in the query builder:

# Friends of friends (1 to 3 hops)

    stmt = select().match(
        (User.alias("a"), FRIEND.variable_length(1, 3), User.alias("b"))
    ).where(
        User.alias("a").user_id == 1
    ).returns(
        User.alias("b")
    )

Generates: `(a)-[:FRIEND1..3]->(b)`

*Variants:* - Unbounded: `FRIEND.variable_length()` → `` - Exact length: `FRIEND.variable_length(2, 2)` → `2` - Min only: `FRIEND.variable_length(1)` → `1..` - Range: `FRIEND.variable_length(1, 3)` → `*1..3`

You can also use the explicit `VariableLength(FRIEND, 1, 3)` constructor if you need to alias the path or reference it later in the query.

The builder handles all edge cases (empty paths, cycles) the same way RedisGraph does — we compile to idiomatic Cypher without abstraction leaks. Raw string patterns still work if you need something exotic.
