(* This file implements proof block detection for:
- blocks delimited by { and }
- bullets with indentation

It exports utility functions to ease the development of other proof block
detection code.

(** A goal is simple if it nor depends on nor impacts on any other goal.
This function is used to detect, dynamically, if a proof block leaks,
i.e. if skipping it could impact other goals (like not instantiating their
type). `Simple carries the list of focused goals.
