Clojurians Log v2

Hey. I was fiddling with evil mode and I found that I could define my own text objects. So I figured I'd define one for clojure's set. But there is a problem. The matching mechanism accepts only one symbol and I want to use two: #{.

(evil-select-paren "#{" ?} beg end type count t)
