The std.stream module documentation doesn't give any clues as
to what an alternative might be.
I have this sort of code:
this(InputStream input)
{
int line_no = 1;
foreach (char[] line; input) {
Am I right in thinking to use std.stdio with an InputRange?
At this point, you pretty much have three options:
1. Use std.stdio.File and read it in in pieces (e.g. with
byLine or
byChunk).
2. Read the whole file in at once with std.file.read or
std.file.readText.
3. Use std.mmfile.MmFile to mmap the file so that the parts
that you access get read into memory, and the rest don't get
loaded from disk, but you get to operate on the whole file as
if you had read it all from disk.

Thanks Jonathan. I don't quite see what I want to do though.
In order to abstract the file aspect of things away, and deal
with a stream of chars that could be from a file, or some some
other source would I use a range?
what I am after is a replacement for InputStream, I don't really
want to directly use File in most places.
So far I have this, and it seems to work, but it doesn't seem
right:
this(InputRange)(InputRange input)
{
int line_no = 1;
foreach (char[] line; input.byLine()) {
...
I have a used a template, because I cannot directly use the
InputRange(char) interface as a type, and auto won't work either,
so is there another parameter type I can use, such that I can
have the concept of an abstract stream of bytes.
