The problem here is likely because var _must_ be known at compile time when you initialize it directly, and stride apparently doesn't work with CTFE. I believe that it's the case that _most_ range-based functions don't work with CTFE yet. So, you'll need to initialize it in a module constructor. So, to get the type, you'll probably need to do something like typeof(stride([1, 2, 3], 2)) var; - Jonathan M Davis
