I'd be happy with either one. :) In both cases, I want to specify a custom vertex type.
Except an abstract type isn't a custom vertex type...
I can either do that directly if the library permits, though I think the solution with associated types is too cumbersome to be useful for my make example.
Why?
Or I get an abstract Node type and the library provides just the right functions that make it easy to manage a custom vertex type myself. I had hoped that the Data.Graph.Inductive.NodeMap module provides this, which it doesn't.
Not sure I follow what you're saying here; then again, my graph stuff has typically been to create the graph and then do stuff to it _as_ a graph (and not wanting/needing to get a specific node based upon its label, etc.).
You're right, I now realize that this design doesn't work. But you asked for wishes, so I wished for something. ;)
Heh, fair enough, except I didn't ask for wishes, just what people would like to see ;-) -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
