Indeed. It should operate on ranges without caring where they 
came from (though it may end up supporting both input ranges and 
random-access ranges with the idea that it can support reading of 
a socket with a range in a less efficient manner or operating on 
a whole file at once as via a random-access range for more 
efficient parsing).

But if I/O is a big concern, I'd suggest just using std.mmfile to 
do the trick, since then you can still operate on the whole file 
as a single array without having to actually have the whole thing 
in memory.
