Nope, functions must have an argument. The normal idiom when calling a
niladic function is to use '' (empty string) as the argument, since it's
easy to type and doesn't require surrounding spaces.

Is it possible to define a nullary function in J? In other languages
they're sometimes convenient, for example a function that returns a
random element. It's a bit awkward to have to use a dummy argument, like
randdie =: 1 + ? @: 6:
which must be called like
randdie 0
and when used in a tacit definition must be called like
randdie ].
