Here is an example of use:
```
require import AllCore.
type t = [
A of int | B of bool | C
].
module M = {
proc f(x : t) : int = {
var y : int <- 0;
match x with
| A v => y <- `|v|;
| B _ => y <- 1;
| C => y <- 2;
end;
return y;
}
}.
lemma L : hoare[M.f : true ==> 0 <= res].
proof. by proc; sp; match => [v|b|]; auto=> /> /#. qed.
