There are no "niladic functions" in J. n v1 v2

I said "niladic function" in analogy to the use of [:
in forks: the case is indistinguishable from arguments
not being passed to the left tine.
That said, I do understand that noun"_ v v is an
equivalent phrase -- and I understand that my
free association might distract some people from
seeing that.
On the other hand, I should also point out that
"niladic functions" which do not produce constant
results aren't really functions. Which is to say:
from my point of view "niladic function" and "noun"
mean basically the same thing -- despite the use
of that phrase to mean something different in the
context of APL.
