From the abstract: Here, we present Codon, a domain-extensible compiler and DSL framework for high-performance DSLs with Python’s syntax and semantics. Codon builds on previous work on ahead-of-time type checking and compilation of Python programs and leverages a novel intermediate representation to easily incorporate domain-specific optimizations and analyses.
