[borkdude]

This works:

$ clj -e "\`~(let [x 1] x)"
1

But this doesn't:

$ lein run "\`~(let [x 1] x)"

In the branch macro-defn-fix this now works:

borkdude@MBP2019 ~/Dropbox/dev/clojure/babashka/sci (macro-defn-fix) $ lein run "\`~(let [x 1] x)"
1
borkdude@MBP2019 ~/Dropbox/dev/clojure/babashka/sci (macro-defn-fix) $ lein run "\`[~@(let [x 1] [x x])]"
[1 1]

$ lein run "\`[~@(for [x [1 2 3]] x)]"
[1 2 3]
