I totally agree and personally love using -> and ->> but I've heard people say that the idiomatic way is to use let instead:

    (let [fortythree (+ 1 42)
          foo33      (foo 33 fortythree)
          bar12      (bar 12 foo33)
          baz33      (baz 33 bar12)]
       baz33)

I understand the logic behind preferring let and a lot of times it really does make things clearer to have everything named and explicit, but especially in prototype code, I find the need to name things to get in the way. I would prefer not naming things over badly named things, for example, and that's usually how I decide between let and thrush (all things being otherwise equal).
