There are set of range interfaces that can be used to mask range 
type. Check for 
https://dlang.org/library/std/range/interfaces/input_range.html 
for starting point, and for 
https://dlang.org/library/std/range/interfaces/input_range_object.html for wrapping any range to those interfaces.

Note: resulting wrapped range is an object and has reference 
semantics, beware of using it directly with other range 
algorithms as they can consume your range.
