(I guess the example I gave was module functions not local 
functions, although the same thing happens with functions 
that are local to a method.)

Yes, there seems to be some interface between having 'first 
class functions' and allowing the convenience of not needing 
() for a method invocation.

If 
   int f() = 5;
   int i = f;
then how would we assign the function to a variable?
   void->int fun = f;


Of course, the same thing crops up for calls to Java static 
methods:

import java.text.*;
void main(String[] args){
   let m = NumberFormat.getAvailableLocales;
   println(m);
}

I like the convenience of not needing to use () but I like 
consistency more. It would be nice if the way a function was 
invoked was clearly different from the way a functional was 
referenced. (Maybe I just don't understand how to do that.)

This is a bug but i'm not sure whether this code should just 
work or throw an error/warning becauce the () are missing.

When leaving () away is possible and what it means should be 
discussed because the exact rules for this are not known and 
I don't think the current implementation is consistent.
