Nice... thanks; I probably had seen code using 'sum' to flatten but hadn't 
actually understood how it worked.  After playing around some it's now 
clear...

(Add one more opening bracket to your solution to make the interpreter 
happy -- I know you know this and it was missed only due to not actually 
trying it ought)
