Do you remember what the reason that you went with a linked list in that case? I’ve been learning hare and was curious about where to use them.

Also, did you use a nullable pointers to represent the next node element in the linked list? Or a tagged union of ( ptr | void)? Or something else?

Yep. I used it in a kernel to create a linked list of statically allocated data structures in a context where dynamic allocation was off the table. You can see the code here:

Went with nullable pointer types, which is also a rarely used feature in Hare.
