The syntax X,Y for object application is indeed a bit strange.
It is a funny use of comma, which in most languages is an
argument separator.
People with habits from other languages (like Prolog, whose
tuples have commas) often make this mistake at first. Even
now, I sometimes write lists like [1,2,3] when I'm in a hurry.
