Well, to give you an idea of what it did, here's the method I had to write
toreplace the functionality:

    def data_map(self,ids):
        result=[]
        for id in ids:
            result.append(self.data[id].__of__(self))
        return result

self.data is an IOBTree.

If this can be replaced wiith a simple return map(...,self.data), please let me
know :-)
