You wouldn't, because Haskel's way is more regular and makes a lot of
sense: parentheses are for grouping and that's it.
If f is a function which normally takes (for the sake of the argument)
one argument, then f would call the function with no arguments (which may
return a curried function, or may apply default arguments, or perhaps
raise an exception). So how would you refer to the function itself
without calling it?
Thanks to Referential Transparency, a function with no params is a constant.
But that's a good observation. It would cause some problems in Python.
ML languages use the empty tuple: f().
