* Removed redundant `.clone()` operations on inner data inside `get_func` and `get_variable` when mapping `ContextValue`. * Refactored `value` to perform a single `.get(name)` lookup rather than doing `is_none()` followed by `unwrap()`. * Avoided holding `MutexGuard` across `func(Vec::new())` execution, thus dropping the lock early and preventing potential deadlock. * Documented the learning in `.jules/bolt.md`.

Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the performance of the Context manager by streamlining variable and function lookups. It achieves this by eliminating redundant data cloning and optimizing hash map access patterns, which collectively reduce unnecessary allocations and decrease the duration of lock contention during high-throughput expression executions.

Code Review
This pull request effectively optimizes the Context manager by removing redundant .clone() calls and eliminating double hash map lookups, which improves performance by reducing allocations and lock contention. The changes in src/context.rs are well-implemented. I've added a couple of suggestions to further improve code conciseness by using if let for pattern matching, which is a common idiom in Rust for these scenarios.
| let value = self.get(name)?; | ||
| match value { | ||
| ContextValue::Function(func) => Some(func.clone()), | ||
| ContextValue::Function(func) => Some(func), | ||
| ContextValue::Variable(_) => None, | ||
| } |

For better conciseness and readability, you can use if let to destructure the Option and the ContextValue in a single step. This avoids the intermediate value variable and the separate ? operator and match statement.
| let value = self.get(name)?; | |
| match value { | |
| ContextValue::Function(func) => Some(func.clone()), | |
| ContextValue::Function(func) => Some(func), | |
| ContextValue::Variable(_) => None, | |
| } | |
| if let Some(ContextValue::Function(func)) = self.get(name) { | |
| Some(func) | |
| } else { | |
| None | |
| } |
| let value = self.get(name)?; | ||
| match value { | ||
| ContextValue::Variable(v) => Some(v.clone()), | ||
| ContextValue::Variable(v) => Some(v), | ||
| ContextValue::Function(_) => None, | ||
| } |

Similar to get_func, you can use if let here to make the code more concise and arguably more readable by combining the check for Some and the destructuring of ContextValue.
| let value = self.get(name)?; | |
| match value { | |
| ContextValue::Variable(v) => Some(v.clone()), | |
| ContextValue::Variable(v) => Some(v), | |
| ContextValue::Function(_) => None, | |
| } | |
| if let Some(ContextValue::Variable(v)) = self.get(name) { | |
| Some(v) | |
| } else { | |
| None | |
| } |

💡 What: Optimized variable and function lookups in the
Contextmanager by reducing.clone()calls and eliminating double hash map lookups.🎯 Why: The original logic in
src/context.rsunnecessarily cloned already-ownedValueandArcdata in.get_func()and.get_variable(). Furthermore,.value()performed an.is_none()check before doing an.unwrap(), triggering two map lookups and unnecessarily keeping the lock held across long-running closures.📊 Impact: Expected reduction in unnecessary allocation and locking duration for high-throughput expression executions.
