Should I use 'let' in my REPL Haddock examples?

What is the correct idiom for assignments in Haddock REPL examples? Specifically, should I use let 

>>> let x = 5
>>> x + 2
7

(as is — still — expected by GHCi) or omit it 

>>> x = 5
>>> x + 2
7

(as I can in IHaskell)?

I believe you should write your snippets for GHCi, which de facto is the standard REPL. As it stands, that means using let. Somewhat arbitrary example: Control.Foldl documentation (libraries by Gabriella Gonzalez provide good examples of "haddocks done right").
