What does the following return?
(let ((bar "bar"))
(helm-aand bar
(replace-regexp-in-string "b" "f" it)
(replace-regexp-in-string "f" "o" it)))
If it returns "oar" then it applies replacements sequentially,
and we have no problem with such implementations.
But we need an alternative version that performs simultaneous
replacements and returns "far".
