Why do function definitions require parens?

This seems to me to break a symmetry with class definitions. I assume this is just a hold off from C, perhaps there is a non-historical reason tho.
The parentheses are always required when calling the function, so it makes sense to always require them when defining the function.
The case with class definitions is different; they are used in the definition only when you want to specify the superclass.
