Okay, thanks for that.  I added the extra module, and found I made
a typo.  So I corrected that too.  Anyways, I am now having another
problem.  What can I do to fix it? :




import std.stdio, std.string, std.array;

void main() {
  uint[string] dictionary;

  foreach( line; stdin.byLine()) {
    // Break sentence into words
    // Add each word in the sentence to the vocabulary
    foreach( word; splitter(strip(line))) {
      if( word in dictionary) continue; // Nothing to do.
      auto newID = dictionary.length;
      dictionary[word] = newID;
      writeln( newID, '\t', word);
    }
  }
  return;
}
