Hi,
I'm trying to see if regions is appropriate for FFI interfaces. I need to allocate some sequences and pass it to FFI functions and later, dealloc them. Currently, GC_Ref and GC_Unref is an option, but still a bit unintuitive and have to be very careful for every allocation. With regions, theoretically I can allocate a bunch of stuff from the same region and later free all of it in one call.
