Re: [Haskell-cafe] Transactional in-memory model

I want the API to allow making changes only to the model and then applying them back to the filesystem at once. This is to support UI where the user will make various changes and then hit "Apply" or "Cancel". I am imagining this as a sort of simple transactional behaviour of the in-memory model.

Vlcak, would the STM constructs in GHC 6.4 be suitable for your project? jake
