Does filter support multiple arguments for the predicate?(i.e. 
using a function that has a "bool function(T1 a, T2 b)" prototype)
If not could still implement the function inside the loop but 
that would be unwieldy.
And does it create copies every call? this is important because 
if i end up using .filter it will be called a 6 to 8 digit number 
of times.
