Pretty-printing D arrays with Mir

I often print arrays to see how they look and their contents.
NumPy has a nice way of pretty-printing the arrays, and I was 
lacking this in D.
For the sake of practice, I wrote a small package. It uses 
mir.ndslice but works for both standard D arrays and Mir Slices.

import pretty_array;
import mir.ndslice;
import std.stdio;

void main() {
     auto b = [2, 2, 6].iota!int(1).fuse;
     b.prettyArr.writeln;
}
┌                   ┐

│└                 ┘│
└                   ┘

There are of course a couple of things to finish like floating 
precision and small number suppression.
Still, hope somebody will find it handy.
