[Haskell-cafe] zipper for rose trees? (Data.Tree)

[Krasimir Angelov]

Hi Graham,

There is one implementation here:

http://code.haskell.org/yi/Data/Tree/

I wrote it for Yi but it is quite general. It is a pity that we don't
have it in the standard libraries. It is not completely tested but it
seems to work for me.

Regards,
  Krasimir
