Hi, I have a problem with the data constructor NodeMap Data.Graph.Inductive.NodeMap of the graph library fgl-5.4.2.3 (also fgl-5.4.2.2):
I cannot access the data constructor NodeMap, as the ghci session shows: Prelude> :m Data.Graph.Inductive.NodeMap Prelude Data.Graph.Inductive.NodeMap> :t NodeMap <interactive>:1:0: Not in scope: data constructor `NodeMap' However, when I load the source directly it works: Prelude> :l Data/Graph/Inductive/NodeMap.hs [1 of 3] Compiling Data.Graph.Inductive.Graph ( Data/Graph/Inductive/Graph.hs, interpreted ) [2 of 3] Compiling Data.Graph.Inductive.Internal.FiniteMap ( Data/Graph/Inductive/Internal/FiniteMap.hs, interpreted ) [3 of 3] Compiling Data.Graph.Inductive.NodeMap ( Data/Graph/Inductive/NodeMap.hs, interpreted ) Ok, modules loaded: Data.Graph.Inductive.Internal.FiniteMap, Data.Graph.Inductive.Graph, Data.Graph.Inductive.NodeMap. *Data.Graph.Inductive.NodeMap> :t NodeMap NodeMap :: (Ord a) => FiniteMap a Node -> Int -> NodeMap a Why is that so? Afterall, my purpose is to get access to the map in a NodeMap and finally to apply lookup to it. But I don't know how to access the map from a NodeMap (the map selector isn't accessible either).
