This seems to be true of any range function really... is there
a way to access the key within my range?
Example of what I want to do:
auto x = [1,2,3,4,5];
x.filter( x_key % 2 == 1 ).sum(); // sum odd elements in array
x.filter!(x_key => x_key % 2 == 1).sum();
Oh man, I really messed up my example, and did a poor one at that.
Better example:
auto x = [2,4,6,8,10];
x.filter( x_key => x_key % 2 == 1 ).sum(); // sums 2 + 6 + 10 ==
18
