Hello,=20

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 implem=
entation. Unfortunately, Bigloo=E2=80=99s support for call/cc is poor, so t=
his library instead provides 2 different, non call/cc-based coroutine imple=
mentations. The native backend implements coroutines via the makecontext fa=
mily of procedures, and the jvm backend uses a thread-based implementation.=
 I am certain there are still some rough edges and would appreciate any fee=
dback, 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 consi=
dering just supporting the thread-based implementation for both the native =
and jvm backends.
Thank You,Joseph Donaldson=20
