You can iterate through a file one ubyte at a time using `byChunk` and `joiner`:

    auto r1 = stdin.byChunk(1024).joiner;
    assert(is(typeof(r1.front) == ubyte));

You can iterate through a string one ubyte at a time using `representation`:

    auto r2 = "To be or not to be".representation;
    assert(is(typeof(r2.front) == immutable(ubyte)));

To pass these ranges around using the `InputRange` interface, use `inputRangeObject` to wrap them:

    InputRange!ubyte r3 = inputRangeObject(r1);
    InputRange!(immutable(ubyte)) r4 = inputRangeObject(r2);

Aha - inputRangeObject was the thing I was missing. Thanks!
