The "dual" problem can also exist in this interpretation of notation,
though:

Would a partial application of `*' to no arguments result in a function
multiplying the product of the arguments (with 1), or would it result in
a function raising an error?  What would this function applied to no
arguments return?

What would the partial application of `-' to a number return when
applied to no arguments?  Etc.
