Hello there,
I was wondering what the recommendations would be for getting CAS on
[mutable] vector elements?
I thought that as a first step I might create an a library that does the
trick only for unboxed vectors, by using bits-atomic (i.e. FFI + GCC

For boxed arrays you need a PrimOp of course (like catMutVar#). For unboxed

could be inline. But to get

Yes.
I normally use an unboxed array of length 1 for these. There's not much
overhead - only an extra word in the heap compared to implementing
