WIP: future

[frenchy64]

Test file: compiler+runtime/test/bash/future/src/jank_test/future.jank

(ns jank-test.future)

(defn -main []
  (dotimes [_ 100000]
    (let [atm (atom [])
          ; on macos, removing gensym gives: Exception: invalid object type: unknown raw value 72
          ; with gensym, gives:
          ; - zsh: segmentation fault 
          ; - zsh: bus error
          a (future (swap! atm conj (gensym "a")))
          ;; b fires twice! a not at all.
          b (future (swap! atm conj (gensym "b")))]
      @a
      @b
      (prn @atm "DONE"))))

On macOS I get all sorts of weird behaviors and errors. "b" conj's twice most of the time if I remove the gensyms.

...
["a" "b"] "DONE"
["b" "b"] "DONE"
["b" "b"] "DONE"
["b" "b"] "DONE"
["b" "b"] "DONE"
["b" "b"] "DONE"

["b" "b"] "DONE"

Exception: invalid object type: unknown raw value 72

Adding the gensyms:

On Ubuntu, conj's happen in the right order, but unknown types happen often:
