Good idea! But I think it needs more ranges:

The format call can be substituted with writefln directly:

void main(string[] args)
{
    import std.algorithm, std.format, std.stdio;
    enum cols = 16;
    args[1].File("rb").byChunk(16).each!(chunk =>
        writefln!"%(%02X %)%*s  %s"(
            chunk,
            3 * (cols - chunk.length), "",
            chunk.map!(c =>
                c < 0x20 || c > 0x7E ? '.' : char(c))));
}

Very cool!
Now you can remove: std.format,
and I would substitute: byChunk(16) with byChunk(col)

Can you point me to the explanation of this: %(%02X %)%*s  %s  ?
