(** PVS printer *)

QUESTIONS FOR THE PVS TEAM
--------------------------
* tuples (there are native tuples in Why3)
- in Why3, we have 0-tuples as well, i.e. a type "()" with a single
value also written "()"
currently, I'm using
tuple0: DATATYPE BEGIN Tuple0: Tuple0? END tuple0
- it looks like PVS does not allow me to perform pattern-matching (CASES)
on tuples i.e something like
CASES x1 OF
(x2, x3): ...
ENDCASES
so I'm doing that instead:
LET x2 = x1`1, x3 = x1`2 IN ...
* pattern-matching
- is there a catch-all pattern in PVS's CASES construct?
Note: I tried to use _ (as in ML and in Why3) and it made PVS go wild!
* I intend to use the script "proveit" to replay PVS proofs (when they exist)
What is the canonical way to check that all proofs have indeed been
successfully replayed?
TODO
----
* eliminate mutual recursion in PVS driver
*)
