I should have thought it was pretty obvious that method 2 creates a list
and then performs an indexing operation on it. These are completely
unnecessary operations, which are avoided in method 3 which is a simple
parenthesised expression.

So why anyone would want to adopt method 2, which is also mess clear as
source code, is beyond me.
