[Haskell-cafe] Re: Looking for practical examples of Zippers

Thanks Don, I followed some examples but have not yet seen anything that would show me how, for instance, turn a nested Map like Map Int (Map Int (Map String Double) into a "zipped" version. That is presuming of course that this use is feasible at all. Günther Don Stewart schrieb:

xmonad's state is represented as a zipper on nested lists.

The wikipedia article on zippers lists this and other examples.

Hi,

my quest for data structures continues. Lately I came across "Zippers".

Can anybody point be to some useful examples?

Günther
