Comments in the REPL cause reader exception errors.

[Ilazki]

Title says it all. Semicolons and #_ syntax generate reader exception errors, only (comment) does not. Example from the Lumo REPL:

cljs.user=> ;; Comment
#error {:message EOF, :data {:type :reader-exception}}
cljs.user=> (+ 2 2) ; Comment
4
#error {:message EOF, :data {:type :reader-exception}}
cljs.user=> #_(+ 2 2)
#error {:message EOF, :data {:type :reader-exception}}
cljs.user=> (comment (+ 2 2))
nil

And here's what happens in Planck, which behaves more reasonably:

cljs.user=> ;; Comment
cljs.user=> (+ 2 2) ; Comment
4
cljs.user=> #_(+ 2 2)
cljs.user=> (comment (+ 2 2))
nil

It's a minor thing I noticed it when I pasted some code in, comments and and all. Found it surprising that Lumo started spewing errors at me, since I've never had Clojure or Planck react badly to comments.
