I modified slightly to avoid parenthesis within quotes or double quotes

  def get_fns(string, count=0)
     m = /(?<fn>
             fn:[\w\-]+
             \s*\(\s*
                 (\g<fn>|(".+")*('.+')*[^)]*)
             \s*\)
         )\s*/xi.match(string)
     if m
         n = /^(fn:[\w\-]+)(\s*)\((.*?)\)$/.match(m['fn'])
         puts "FN #{count}: #{n[1]} with args #{n[3]}"
         get_fns(n[3], count + 1)
     end
  end
