Two major threads converged today in the Cx language project, making a significant technical leap forward. The IR backend refactor has finally merged into main, transitioning the Backend trait interface from raw AST to a more robust IR. Simultaneously, over at submain, a newly introduced 301-line module resolver is set to redefine how we handle dependencies, circular imports, and topological sorting. IR is now the backend interface March 24th saw the successful merge of PR #19, a union of four commits that ushered in Phase 0.5 of our backend architecture changes. The crux? Moving the Backend trait from using &Program (AST) to &IrModule (IR). With this one-way door, all backend development now requires IR input, no turning back to the AST-based approach. Cranelift and LLVM backends received immediate updates in response. The additional commits introduced vital debugging tools for the IR pipeline. These might not seem groundbreaking, but when you need to diagnose a validation fai
