I am currently searching for implementations of Huet's Zipper ``in the wild''.
So far, I have found:
The agda compiler (correct me if I'm wrong) uses the zipper for the eliminator of call-by-need evaluations, filling out information as it goes.
Another instance is used in XMonad to keep track of the focused workspace and the focused window on each workspace
Are there other ways to implement//other implementations of the zipper?

Is there an equivalent of Data.Lists.NonEmpty for sets?
I know there is NonNull from mono-traversable, but I'm wondering if there's anything else out there.
Not in base, but there does seem to be a package that includes nonempty versions of a few data structures, such as Maps and Sets.

I'm looking for a way to derive fmapFirst and fmapSecond for bifunctors automatically. I would prefer a way to do it using the new Generic type class or using Data.Data, and without Template Haskell.
(Note that I already know that https://hackage.haskell.org/package/genifunctors-0.2.2.0/docs/Data-Generics-Genifunctors.html supports this with use of Template Haskell, I wish to know if Template Haskell can be avoided here)

I've seen such diagrams on many websites, including HgInit and I like the looks of them.
The sketching style looks similar to Balsamiq Mockups software

Does anybody know of a good SVG parser that puts out an SVG object in C++? I don't mind if it's free or paid. I'm just looking for one that is cleanly architected and adheres very well to the spec. Preferably one that would let me start rendering by just inspecting the structures and passing the info on to Cairo or QT.
Thanks!
Maybe you should have a look at the Fog-Framework

I know M is a new language from Microsoft that's targeted as a modeling solution but I'm still a bit fuzzy on usage / rationale / advantages. That's why I'm looking for interesting things that people have done with M, so I can understand it better.
Well it's new, as you said, so you'll have a hard time finding thing already done. Your best bet would probably be to see how Microsoft itself uses the language.
