It's not that simple. The function has to be reversible, so that when a filepath in a view is changed, git-annex can calculate a delta to apply to its metadata. Also, the function must be guaranteed to never assign the same filename within the view to two files from its parent branch. These are some pretty hairy constraints, which led to the current implementation. Of course it can be modified using a function, as long as the function is written in haskell. ;) See Annex/View/ViewedFile.hs -- see shy jo
