Comparisons between a range and a static array gave error.

The error received is:

    Error: incompatible types for ((small) == ([1,2])): 'Filter!(result,int[])'
and 'int[2u]'

Example code provided by std.algorithms webpage:

import std.algorithm;

void main() {
   int[] arr = [ 1, 2, 3, 4, 5 ];
   // Sum all elements
   auto small = filter!("a < 3")(arr);
   assert(small == [ 1, 2 ]);
}
