Clojurians Log v2

Hey all - in CLJS, I've implemented  `IPrintWithWriter`  for a js type called `Fraction`, and for some reason the repl, when printing, refuses to show a space:

;; implementation
(write-all writer "#sicm/frac " (str x))
(rationalize 1 10)
;; => #sicm/frac(/ 1 10)

pr-str does the right thing:

(pr-str (rationalize 1 10))
=> "#sicm/frac (/ 1 10)"

any escaped characters like `\"` cause it to stop printing. I was trying to get the repl output to match pr-str and print #sicm/frac (/ 1 10), with a space... any thoughts on what I'm doing wrong here?

this is with:
