Property assignment syntax for non-property functions is a 
horrible, horrible thing.

Could someone please explain what is actually happening in that 
piece of code to a D newbie?
I see what happens when I run the code but I don't get why it is 
happening.
In particular what "register = true;" actually does in that case.

Thanks,
