In D, .name means "look up name in the global scope". Since 
factorial is in the global scope, it found it successfully and 
everything worked.

The place this would be useful is something like this:


int a = 10;

void foo() {
    int a = 20;
    writeln(a); // 20
    writeln(.a); // 10 - the dot tells it to use the global 
instead of the local
}
