fun(bool, bool, bool, bool, bool...)
Isn't the type clear for every argument here?

Reordering is important an example:

fun(int a, int b=2, int c=3)
If you want to name c but not b what are you going to do?

Named arguments isn't something to save typing.
Also the first version of the MoveWindow indeed worse than the second,  
which again i think requires no explanation.
