I introduced references into lcc-win because they are useful.
Beyond this guy trolling here, his discussion allowed me to plug a hole
in my implementation, you could actually write

int fn(void &foo);

because lcc-win did not test explicitly for a void pointer.

Now I wonder what other problems may be lurking in my implementation there.


References allow you to use a much safer kind of pointers than plain 
ones. They must be initialized at their definition point, and they can't 
change afterwards, they always point to the same object.

Now, if you get a reference into a function it is NOT necessary to test 
for NULL since references can never be NULL.

This is obviously an extension but I think it is justified.
