My own personal opinion is that it makes sense in combination with 'and',
but others may feel differently.  E.g.,

    (when-let [a (allocate-thing) b (read-into-thing a) c
(extract-something-from-thing b)]
      (do-something-with c))

makes intuitive sense to me.  If, at any stage of the execution, any of a,
b or c was nil, the evaluation would stop and the (when-let) form would
return nil.
