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;
}
