TL;DR
Developers have announced Jolt, a new Clojure compiler built with Chez Scheme. This change aims to improve performance and interoperability, with further details pending.
The Clojure programming language now has a new compiler called Jolt, which has been implemented entirely with Chez Scheme. This development, announced by the project maintainers, aims to enhance performance and improve interoperability with other Scheme-based tools.
The Jolt compiler is a reimplementation of the existing Clojure compiler, built from scratch using Chez Scheme, a high-performance implementation of the Scheme language. The project was officially announced in March 2024 by the Clojure community, with developers citing potential benefits in execution speed and easier integration with Scheme ecosystems.
According to the Jolt project team, the transition to Chez Scheme allows for more efficient compilation processes and better support for advanced language features. They also highlighted that this move could facilitate future enhancements and experimental features, leveraging Chez Scheme’s mature and optimized runtime.
Potential Impact on Clojure Performance and Ecosystem
This shift could significantly influence the performance of Clojure applications, especially in environments where execution speed is critical. By leveraging Chez Scheme’s mature infrastructure, Jolt aims to reduce compilation times and improve runtime efficiency.
Furthermore, this development might open new opportunities for interoperability between Clojure and other Scheme-based tools, potentially expanding the language’s ecosystem and use cases. However, the long-term impact remains uncertain until more performance benchmarks and community feedback are available.

Background on Clojure and Chez Scheme Integration Efforts
Clojure has traditionally been implemented on the JVM, providing portability and access to a vast Java ecosystem. Recently, however, there has been interest in alternative implementations that could improve performance and flexibility.
Chez Scheme is a high-performance, portable Scheme implementation known for its efficient compiler and runtime. Prior to Jolt, there have been experimental efforts to integrate Clojure with other Scheme implementations, but none as comprehensive as this reimplementation using Chez Scheme.
The announcement of Jolt marks a notable shift towards exploring non-JVM implementations of Clojure, reflecting broader community interest in language performance and interoperability.
Unanswered Questions About Jolt’s Performance and Compatibility
It is not yet clear how Jolt’s performance compares to the traditional JVM-based Clojure in real-world applications. Community testing and benchmarking are ongoing, and compatibility with existing Clojure libraries is still being evaluated.
Additionally, the extent to which Jolt will support all current Clojure features remains uncertain, as the project is still in early development stages.
Next Steps for Jolt Development and Community Adoption
Developers plan to release beta versions for testing within the next few months, focusing on benchmarking and compatibility. Community feedback will shape future improvements, and the project team aims to establish a stable release by late 2024.
Further collaboration with the Clojure community and Scheme ecosystem developers is expected to explore integration possibilities and optimize performance.
Key Questions
What is Jolt?
Jolt is a new Clojure compiler implemented entirely with Chez Scheme, aiming to improve performance and interoperability.
Why switch to Chez Scheme?
Chez Scheme offers a high-performance compiler and runtime, which can potentially make Clojure applications faster and more flexible.
Will Jolt replace the existing Clojure compiler?
It is too early to say; Jolt is currently in development and aims to complement or eventually replace the existing compiler if successful.
How will this affect Clojure developers?
Initially, developers may test Jolt for performance and compatibility; widespread adoption will depend on stability and feature support.
When will Jolt be available for general use?
The project team aims to release a stable version by late 2024, after thorough testing and community feedback.
