Although not exactly aesthetically pleasing, I actually prefer the 1. 1. 1. layout. Why? Because when you write something it's common to revise and re-order things. A lot. Having 1. 2. 3. means I'd have to go and fix the rest of the list.

I see 1. 1. 1. like appending commas to every field in a struct declaration or an object constructor. It allows me to go back and arbitrarily move things around.
