New convenience procs have been added for doing fast operations on associative lists that hold numbers as their associated values, such as list("apple"=3, "orange"=10). This is mainly to drive performance in certain games.

The new procs are:

• values_sum: Returns a total of all associated numbers in the list
• values_product: Returns a product of all associated numbers in the list (1 if no numbers)
• values_dot: Returns a dot product of the numbers in two associative lists, by multiplying the numbers associated with matching values
• values_cut_under: Cuts all values from a list whose associated numbers are below a certain threshold
• values_cut_over: Cuts all values from a list whose associated numbers are above a certain threshold
