Good idea! But I think it needs more ranges:

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