You're aware of the kludge that prevents you putting a newline before
the ( when calling a function? Allows table constructors to be
prefixexps would have exactly the same problem, e.g:

   -- One statement or two?
   x = f
   { ... }[i]()

Except it's more likely that you'd want a newline there, e.g.

   some_configuration_directive
   {
       ...
   }
