Although a standard reader macro for infix syntax would be a nice
thing to have in Clojure.
It could be #[...] or something like that. I don’t care if it is
#[] or i{} or $() or something else.
But it would be nice to be able to say
say #[14x⁶ - 2√π]
vs (- (* 14 (. Math (pow x 6))) (* 2 (. Math (sqrt Math/PI))))
Or #[Σlist + 19]
vs (apply + 19 list)
or (if #[∀x∈M1: x > 10 ∧ ∃y∈M2: y=4] ...)
vs (if (and (every? #(> % 10) M1) (some #(= 4 %) M2)) ...)
