-(*** Well-founded relations *)
-
-(* We had a few issues when proving termination of the mutually recursive functions:
- * - betree_Internal_flush
- * - betree_Node_apply_messages
- *
- * The quantity which effectively decreases is:
- * (betree_size, messages_length)
- * where messages_length is 0 when there are no messages
- * (and where we use the lexicographic ordering, of course)
- *
- * However, the `%[...]` and `{:well-founded ...} notations are not available outside
- * of `decrease` clauses.
- *
- * We thus resorted to writing and proving correct a well-founded relation over
- * pairs of natural numbers. The trick is that `<<` can be used outside of decrease
- * clauses, and can be used to trigger SMT patterns.
- *
- * What follows is adapted from:
- * https://www.fstar-lang.org/tutorial/book/part2/part2_well_founded.html
- *
- * Also, the following PR might make things easier:
- * https://github.com/FStarLang/FStar/pull/2561
