The right solution is to define yoyo_time in another module:

blah.ml ------------

let yoyo_time = ref 10
let set_yoyo_time newtime = yoyo_time := (int_of_string newtime)

blah.mli ------------

val yoyo_time : int ref
val set_yoyo_time : string -> unit

parser.mly ----------

%{
open Blah
%}

This way you can stay away from touching the scary .mli file generated
by ocamlyacc.
