You have a special understanding of optional.
What a beautifully crafted put-down :)
My reasoning is: if its allowed, even if it is optional -- in fact especially if it is optional -- it should have a default value. Even if that default value is undef.
I do remember some discussion around the possibility of using undef to override a default value, but I decided that such usage was rare and obscure enough that if teh occasion arose it was necessary, I'd had code a solution for it above or below the standard mechanism as appropriate.
I don't mind hand coding a solution for the 1 in 1000 case, if that means the other 999 cases operate in an efficient manner.
