Ok, so I'm trying to replace a ' character with \' in a ruby string. I have working code, but it was 
*way* too painful getting there for my taste.

Take a look:

ree-1.8.7-2010.02 :001 > single_quote = "\'"
 => "'" 
ree-1.8.7-2010.02 :003 > single_quote.gsub(/'/, "\\\'")
 => "" 
ree-1.8.7-2010.02 :004 > single_quote.gsub(/'/) {|c| "\\'"}

(defn recursive-reverse [coll]
  (if (= 0 (count coll)) 
    []
    (concat (recursive-reverse (drop 1 coll)) (take 1 coll))))

(defn recursive-reverse [coll]
  (loop [coll coll
         acc []]
    (if (empty? coll)
      acc
