I noticed in my code that I often nest a let inside an if-let, or vice-
versa, so I wrote a macro let-else that expands into nested lets,
except where there's an :else <expr> after a binding, in which case
that binding expands into an if-let.
E.g.
(let-else
[foo (f1) :else (e)
bar (f2)]
(b1)
(b2))
expands into
(if-let [foo (f1)]
(let [bar (f2)]
(b1)
(b2))
(e))
