I have to say I prefer the emerging form

    	x = if e1 then v1 elif e2 then v2 else v3

The parentheses are certainly not required, and can always be added by 
those who like to use them.

I'm pretty sure that  

    	x = if e1: v1 elif e2: v2 else: v3

will work without the brackets; again, bracket enthusiasts can add them to 
taste!
