array slicing currently does not support steps?

just act like this is syntax in the language and not a function 
call:

auto x = array[0 .. 10].stride(2);

I think readability-wise this beats other syntax you can come up 
with and it's just a library solution :)

If you then want to copy it into an actual array you can pass as 
slice use

auto x = array[0 .. 10].stride(2).array;

or adjust your functions to handle ranges properly :p

On the function implementation side I can definitely see room for 
improvement though, like the signatures DIP rikkimax had once 
made which would make templates not needed for supporting passing 
and storing ranges.
