Does filter support multiple arguments for the predicate?(i.e. using a function that has a "bool function(T1 a, T2 b)" prototype)
I am not sure exactly what you are asking here, but you can probably accomplish what you want by combining filter with std.range.chunks or std.range.slide.

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.
filter does not create any copies of the original array. The same is true for pretty much everything in std.range and std.algorithm.
