tiny.mprompt.promptParent

1/// Returns the next active prompt outward from `p`, or the innermost active prompt when `p` is2/// null, so a caller walks the thread's active prompts outward one step per call, as the runtime3/// does to check that a suspend targets an active prompt. For a suspended `p`, the call returns4/// null or the next prompt outward inside the captured chain.5pub fn promptParent(p: ?*Prompt) ?*Prompt {6    return if (p) |prompt_ptr| prompt_ptr.parent else prompt_top;7}
