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
{
...
}
