Void functions are allowed to have return statements with a return value 
expression, and main is no exception.  I think it's to remove some special 
case stuff regarding templated functions.  The expression is evaluated but 
its value is discarded.  Example:

int foo()
{
 writefln("foo");
 return 0;
}

void bar()
{
 return foo();
}

void main()
{
 bar();
}

prints "foo".
