I was writing a quick-and-dirty library for parsing CSV files, and I can't figure out why I'm getting an "Index out of bounds" error:
char[][] splitAtComma(char[] i) {
  char[][] ret;
  int f = 0;
  foreach (c; i) {
    if (c == ',') {
      f++; ret[f]=[];
    } else {
      ret[f] ~= c;
    }
  }
  return ret;
}

You are accessing elements in ret that don't exist yet. Try something like this (untested):

char[][] splitAtComma(char[] i) { char[][] ret; if (i.length ret.length = 1; foreach (c; i) { if (c == ',') { ret.length = ret.length + 1; } else { ret[$-1] ~= c; } } return ret; }
Or better yet, use tango.text.Util.split. ;)
