What the hell is this 'for else' loop !! :D First time I see this 
statement for years.
I'd never thought I'd still learn something that basic.

My first impression is that the  mechansim is not that obvious. MRAB's 
need for a comment tends to confirm this.
I'll try to remember that anyway. Nice addition.
