I guess I'm not being very clear. I'll try again...

On the first pass, I'd like to suggest that the compiler could 
check for an occurrence of "main" followed by "(" and spit out an 
error if it's not found.

Any of the following would avoid the error:

```
void main(

<returned type> main (

void main  (
```

And other variations thereof.
