Could you include this in the next release? :)

class Symbol
   def to_proc
     proc { |obj, *args| obj.send(self, *args) }
   end
end

It allows you do the following:

(1..10).inject(&:*)                     # => 3628800
%w{foo bar qux}.map(&:reverse)          # => %w{oof rab xuq}
[1, 2, nil, 3, nil].reject(&:nil?)      # => [1, 2, 3]
%w{ruby and world}.sort_by(&:reverse)   # => %w{world and ruby}
