Why is std.algorithm so complicated to use?

err, that should be more like:

auto singletonRange(E)() // with no parameters
{
  return takeNone!type_of(repeat(E.init))();
}

An emptyRange compatible with singletonRange should be called 
singletonRange and take no parameter, so that emptyRange name could be 
reserved to a real statically empty range (which is pretty easy to 
implement).
