Wouldn't this be too small a function to include into the stdlib? Why
not simply include

class String
  def index_of_last(needle)
    self.index(needle) + (needle.size - 1)
  end
end

in your program or your personal lib. Or maybe ask for inclusion in nano.
But I admit its difficult to draw the line here. What is your opinion?

best regards,
