Yes you do. Builtins will be followed by a '('; the variables won't.
(Obviously there can be exceptions, but in practice very, very few.)

It has fewer than most dynamic languages; and remember that I'm
trading product(), any(), all() for reduce(), map() and filter().
There are others slated for disappearance, too.
