In mathematics (except in lambda calculus), there
is generally no such thing since functions
generally have no side effects and hence no-param
function = constant, and name with no parens is
same as normal name ref to constant, whether
number, function, or other mathematical object.
On the other hand, one-param functions *are* ofter
written without parens for simple args.  Hence I
suspect that above would lead to the suggestion
that parens also be optional for single-arg funcs.

The overloading of no-op juxtaposition to mean
either * or () (alternatively, the interpretation
of function * number as function(number)) is
rather cute.
