Thanks, Ivan! It looks exciting. Is there a demo file floating around somewhere? Martin Erwig's old site [1] for FGL includes some demonstration code, which builds on a file called "test.hs" [2]; I know the site is obsolete but are those aspects of it still useful?

[1] https://web.engr.oregonstate.edu/~erwig/fgl/haskell/ [2] https://web.engr.oregonstate.edu/~erwig/fgl/haskell/test.hs

Most of those should still be valid, yes. There's also the Examples module in fgl.

I'm pleased to announce that I've (finally!) just released version 5.5.2.0 of [fgl]. Major changes in this release include a test suite, refactorings, code clean-ups and the following potentially breaking changes (in that they were previously unspecified or incorrect):

- `nodeRange` and `nodeRangeM` for the various graph data structures erroneously returned `(0,0)` for empty graphs (making them indistinguishable from graphs containing the single node `0`). They now match the default implementation of throwing an error.

- The behaviour of `delLEdge` when dealing with multiple edges was unspecified; it now deletes only a single edge and the new function `delAllLEdge` deletes all edges matching the one provided.

All changes can be found in the changelog.

Along with this I'm releasing version 0.2.0.0 of [fgl-arbitrary] (i.e. the "I finally build against the version on Hackage" release).
