Yeah, I found when I first got started with Clojure I tended to use
let for intermediate named results but over time I've moved to using
small, private top-level functions instead because I want to focus on
the names of the _functionality_ rather than the names of intermediate
_data_. I still use let for some things but nowhere near as much as I
used to.
One construct using let that I see in my code quite a bit that I
haven't figured out a cleaner way to express:
(let [x (some-expression)]
(if (p x)
(f x)
(g x)))
I get tempted to write a utility function for it but I haven't come up
with a good name for it :)
