Hello, I have adapted SRFI 158: Generators and Accumulators for Bigloo. It can be found at https://github.com/donaldsonjw/srfi158. Both the Bigloo native and jvm backends are supported. The SRFI 158 library requires coroutines, and the sample implementation, unsurprisingly, leverages call/cc for its implementation. Unfortunately, Bigloo’s support for call/cc is poor, so this library instead provides 2 different, non call/cc-based coroutine implementations. The native backend implements coroutines via the makecontext family of procedures, and the jvm backend uses a thread-based implementation. I am certain there are still some rough edges and would appreciate any feedback, if someone gives it a try. N.B., I have only tested the make-context corroutine implementation on X86-64 Linux, and given that the performance difference, at least in my limited and non-scientific benchmarking, does not seem to be too great, I am considering just supporting the thread-based implementation for both the native and jvm backends. Thank You,Joseph Donaldson
