Replace the prompt with the buffer name in erc buffers

Question

How can I replace the ERC> prompt in every erc buffer so that it shows the name of the buffer instead?

For example if I'm in the #emacs channel, I have this:

   *** arall (~arall@128.205.23.161) has joined channel #emacs  [22:40]   
   ERC> 

While I'd like to have this:

   *** arall (~arall@128.205.23.161) has joined channel #emacs  [22:40]
    #emacs>

You can set variable erc-prompt to function that will return the current channel's name, something like:

(setq erc-prompt  (lambda () (concat (buffer-name) "> ")))
