What someone should implement (ill do it next week or so unless
someone else wants to give it a try) to optimize access speed and the
cost of val_to_str()   is to change
val_to_str() to
1, When we find an entry in a value_string   keep track of the index
into the array in a variable cnt.
2, Swap the entry at cnt (the one we found) with the entry cnt>>1 (IFF cnt!=cnt>>1).
...after de-constifying all the value_string tables; otherwise, modifying the table will get an access failure.
