Breaking ten years of C API compatibility in Futhark

Futhark, a high-performance functional array programming language, is breaking its decade-old C and Python API compatibility to address a long-standing design flaw. This change affects how compiled libraries interact with host languages, requiring updates to wrapper code. The move reflects the project's commitment to long-term improvements despite disrupting stability.

Background

Futhark is a purely functional data-parallel array language designed for high-performance computing, typically compiled to C libraries for integration with general-purpose languages. Its C API has remained stable for a decade, serving as the foundation for language bindings.
