On another note to what others said. An array is only a range 
when std.array has been imported (or passed to a module expecting 
a range which imports std.array).

A range is only a concept, it can not be be stored in an input 
range variable. inputRangeObject is rarely needed and I can't 
give an example of when it would be.
