Nope, not a bug.

In Poke when you refer to a function that does not get arguments, it is
invoked, i.e. given

  fun foo = int: { return 10; }


   var v = foo ();

can also be written as simply:

   var v = foo;

You can refer to the function value (without evaluating) regardless of
the number of arguments it takes by putting it within parenthesis:
