I am not convinced by this argument. The return value (aka exit code) is
always present, if you ignore this by having a void main, it will return
0, i.e. main is not a void function even if you claim it is. As for
ignoring the parameters, this is making use of the fact that main is the
only function where you do not have to present the correct signature.
Perhaps this exception should be removed.

The real signature of main in C/C++ is, I believe:

        int main(int, char**, char**)

what is the real signature in D?
