tl Thread last all
Start with:
(map square (filter even? [1 2 3 4 5]))
Put your cursor in front of the s-exp, and call cljr-thread-last-all:
(->> [1 2 3 4 5]
(filter even?)
(map square))

There is a corresponding cljr-thread-first-all as well.
To revert this, there's cljr-unwind to unwind one step at a time. Or there's cljr-unwind-all to unwind the entire expression at once.
