Of course that argument fails totally in one important
case -- Q: if you wanted a loop why didn't you use one?
A: tail-rec functional code is considered cute :)

I'm sure there are other cases .. would not:

let x = 1 in
let y = 1 in
let z = 1 in ...

be optimised into a single closure, not 3?
Or do i really have to write:

let x = 1 and y = 1 and z = 1 in ..

What's efficient depends on what's optimised which
depends on what idioms are considered 'cute' looking :)

BTW: there is another answer to the question Xavier asked:

Q: why did you write the code that way ..?
A: I didn't, it was generated..

which suggests sometimes there is a reason to optimise
'silly' looking code.
