Descrizione
When command "let" is introduced it is not really explained why it evals through double parenthesis:
> ;; You can bind a value to a local variable with `let':
> (let ((local-name "you"))
> (switch-to-buffer-other-window "*test*")
> (erase-buffer)
> (hello local-name)
> (other-window 1))
