Formatted input from text file

I don't know the cause of your problem. While investigating it I 
have filed another bug:

In the meantime this (a bit scary) code solves your reading 
problem:

import std.stdio, std.algorithm, std.range, std.conv;

void main() {
     const grid = File("table.txt")
                  .byLine().map!(r => std.algorithm.splitter(r)
                                      .map!(to!int)()
                                      .array())()
                  .array();
     writeln(grid);
}
