Ruby's find module usually forces you to pass it a block. This snippet makes it return an array if there is no block. Note: the returning method is from Rails, but this can easily be removed.

require 'find'

module Find
  class << self
    alias_method :find_old, :find
    
    def find(*paths)
      if block_given?
        find_old(*paths, &yield)
      else
        returning ary = [] do
          find_old(*paths) { |p| ary << p }
        end
      end
    end
  end
end
